Description

ELECTRIC-FIELD DETECTION OUTPUT DEVICE, ELECTRIC-FIELD ADJUSTMENT SYSTEM, AND ELECTRIC-FIELD ADJUSTMENT METHOD

[0001] The present invention relates to an electric field detection and output device excellent in simplicity, quickness, precision, and non-invasiveness for measuring, detecting, and outputting an electric field strength or direction simply and accurately.

BACKGROUND OF THE INVENTION Techniques and devices using an electric field or accompanying generation of an electric field are widely used. Also, a strong electric field is generated by natural phenomena such as static electricity or thunder. However, since the electric field is invisible, it is not easy for even an expert or a skilled person to quickly and accurately grasp the electric field of an object. It is difficult for those who do not have specialized knowledge about electric fields, such as users of technologies or devices, to understand and imagine the electric field of the object. For example, in an electric potential therapy device that applies a high voltage to an insulated human body and performs treatment using a biostimulation action by an electric field formed around the human body, the patient to be treated recognizes that an electric field is formed around the human body. it is difficult

Conventional methods for measuring electric field strength and direction are mainly classified into the following two types. As a 1st method, the probe which can detect an electric field is used, and the structure of the electric field measurement apparatus in which a metal probe is connected to a detection system via a metal cable is known. In addition, in order to suppress invasiveness, there is also known a technique related to an electric field measurement device in which a probe tip made of an electro-optic crystal is connected to a photodetector system with an optical fiber cable (see, for example, Patent Document 1). These techniques insert the tip of a probe part into an electric field, and perform electric field detection and measurement. Further, as a second method, the potential of a reference point is measured, the difference (voltage) from the reference potential is measured for one point in the vicinity of the measurement target, and the value obtained by dividing it by the distance between the two points is an electric field. The method is known. Moreover, the technique related to the electrometer which detects and informs the formed electric field is known (for example, refer patent document 2). This technique discriminates the presence or absence of an electric field.

In addition, the electric potential therapy device 200 is a chair shape as shown in Fig. 12, and a plurality of sheets of the upper electrode 2001, the left electrode 2002, the lower electrode (ground) 2003, etc. In addition to the electrodes, a voltage generator 2004 for applying a voltage between the electrodes is provided. A person to be treated receives treatment by sitting in a chair and placing his or her body in an electric field generated between the upper electrode 2001 and the left electrode 2002 (see, for example, Patent Document 3). Here, the voltage generated from the voltage generator 2004 can be adjusted by a human hand.

However, when a metal probe is inserted into an electric field, the electric field to be measured is disturbed by the probe or cable, and high invasiveness is expressed. Here, the invasiveness refers to a property in which the electric field to be measured is disturbed by an external factor.

In the technique described in patent document 1, although invasiveness is reduced, since a structure is complicated and an apparatus enlarges, carrying is difficult and it does not have convenience. In addition, in the technique described in Patent Document 2, by determining the presence or absence of an electric field, the electric field cannot be accurately measured and the intensity cannot be grasped.

In addition, since the electrodes of the potential therapy device 200 are basically fixed in a fixed position, even if the voltage between the electrodes is constant, depending on the physique and body type (height, sitting height, weight, obesity, etc.) The intensity of the electric field applied to each site of the therapist is changing, and the therapeutic effect is also non-uniform.

For example, FIG. 14 is a conceptual diagram of a measurement experiment of electric field strength in each part of the human body by the electric potential therapy device 200 . The electric potential therapy device 200 used for the measurement is input to the upper electrode 2001 and the left electrode 2002, a voltage of 4500 V generated from the voltage generator 2004 is input with a phase shift of 180 degrees, and the lower electrode 2003 is grounded. there is.

Then, _{by using an electro-optical crystal such as Bi 12} SiO ₂₀ and a photoelectric sensor using an optical fiber, the body surface vicinity and the body surface of each part of the human body (head part, forehead vicinity, abdomen, knee part, and foot part) shown. The electric field strength was measured at a location about 12 cm away from it. Alphabet in the figure indicates measurement points, A and B are the head, C, D are the vicinity of the forehead, E, F are the abdomen, G, H are the knees, I, J are the feet, A, C, E, G and I are near the body surface, and B, D, F, H, and J are places 12 cm away from the body surface.

Here, the measurement axis (the electric field of the component in the same direction as the axis is measured) of the photoelectric sensor was set in the direction of the arrow in the figure.

In addition, the physique of the subject P at this time was 175 cm in height, 68 kg in weight, 20% body fat percentage, and a physique index of 22.2.

Table 1 shows the results of this experiment.

As is clear from this result, the electric field strength varies greatly depending on the distance from each part of the body of the subject P or the body surface. In this experiment, although there was only one to-be-treated, it can be easily guessed that the measured electric field intensity|strength changes even when physique and body shape differ.

By the electric field detection output apparatus 10 is inserted into the field, it intended to notify the field strength, as shown in Fig. 1, and mainly, the electrodes _{(11, 12),} a virtual ground type current detector (2) , LEDs 3 ₁ to 3 ₄ as output means, a battery 4 as a power source, a switch 5 , and a gripping unit 6 .

Electrodes _{(11, 12)} is 1, and, a flat electrode provided in parallel are arranged substantially in opposition as shown in Figure 2, is set to a distance between electrodes (d), the electrode area (s). The electrodes 1 ₁ , 1 ₂ include the virtual ground type current detector 2 , the LEDs 3 ₁ to 3 ₄ , the battery 4 , the switch 5 , and the electrodes 1 ₁ , 1 _{2 .} ), the size (electrode spacing (d), electrode area (s)) and shape are set so that they can be accommodated in the space formed in the space. Further, as shown in Fig. 3, the electrode spacing d is sufficiently small for the length L at which the electric field of the measurement object is regarded as a constant value, for example, for a length L of several 10 cm, Set to a few centimeters or less. In addition, the electrode area s is sufficiently small with respect to the area S in which the electric field of the measurement target is considered to be a constant value, for example, the area S is set to several cm 2 or less with respect to several 10 cm 2 . The electrode (1 _1, 1 ₂₎ are respectively the conductors (E _1, E ₂₎ connected.

Virtual ground type current detector 2, 1, the electrodes _{(11, 12)} is provided disposed between the electrodes _{(11, 12)} to the DC current generated when a charge is an organic Alternatively, it detects an alternating current, and is composed of a current amplifier and a detector having virtual ground characteristics. It has an input terminal (not shown) in the virtual ground type current detector (2), the wire (E _1, E ₂₎ connected to the electrodes _{(11, 12)} are connected. In this way, the virtual ground type current detector 2, and the switch 5 to be described later state "open", and, when the value of the electric field detection output device 10 in the electric field, the electrodes (1 _1, 1 _2), Charges of different polarity are induced, and the current generated at that time is to be detected. At this time, due to the virtual grounding characteristics of the virtual grounding type current detector _{2 , no potential difference occurs in the electrodes 11} and 1 2 , so the electric field detection and output device 10 operates as a metal plate having a thickness d. can be considered to be The virtual ground type current detector 2 outputs the detected current value to the LED 3 ₁ to 3 ₄ side.

Here, the virtual ground characteristic is a characteristic of an operational amplifier (Operational Amplifier), and the voltages at the input terminals of the non-inverting input (+) and inverting input (-) are always the same, that is, the same potential. will become That is, a virtual ground input terminal of the type current detector 2 (the non-inverting input (+) and inverting input (-)), the electrode wire (E _1, E ₂₎ is connected up to the (1 _1, 1 ₂₎ Therefore, the electrodes 1 ₁ , 1 ₂ do not generate a potential difference.

When the electric field to be measured is an alternating current, the virtual ground-type current detector 2 calculates the effective value of an electric current by the following formula|equation. Here, I _rms is the rms value of the current, f is the frequency, ε is the dielectric constant, s is the electrode area, and E _rms is the rms field strength. That is, the calculated rms value I _rms of the current is proportional to the _rms field strength value E rms .

[Number 1]

In addition, when the electric field to be measured is direct current, the virtual ground-type current detector 2 calculates a current value by the following formula|equation. Here, I is the current value, t is the time, ε is the dielectric constant, s is the electrode area, and E(t) is the electric field strength. That is, the time integral of the calculated current value I is proportional to the electric field strength E(t).

[Number 2]

The output means is _{arranged and provided between the electrodes 11} and 1 ₂ and is for outputting the electric field intensity according to the current detected by the virtual ground type current detector 2, for example, LED or liquid crystal The display device includes a display device and a device that outputs (transmits) the electric field strength according to the detected current to an external display device as data. In the first embodiment, the output means is LED (3 ₁ ~3 _4), as is, in Fig. 2, the electrode _{(11, 12)} is provided disposed between the virtual ground type current detector (2) The electric field strength according to the detected current is output to the outside. In the present embodiment _{1, LED (3 1 ~3 4} ) , the electrode (1 _1, 1 ₂₎ are provided in batch are listed in one of four sides of the. Specifically, for example, when the current value detected by the virtual grounding type current detector 2 is zero, neither LED 3 ₁ to 3 ₄ is lit, but the virtual grounding type current detector 2 . When the current value detected by is larger than zero, the number of LEDs 3 ₁ to 3 ₄ to be lit is increased or decreased according to the magnitude of the current value, that is, the electric field strength. That is, by the number of lit LED (3 ₁ ~3 _4), is able to recognize the presence or absence of an electric field and the detected electric field intensity. In here, Figure 2, LED (3 ₁₎ and only the light, LED (3 ₂ ~3 ₄₎ shows a (which is turned off) state that is not lit.

Cell 4, as shown in Figure 2, the electrode _{(11, 12)} is provided disposed between, for supplying power to the virtual ground type current detector (2) and the LED (3 ₁ ~3 ₄₎ and is composed of, for example, a coin-type battery.

Switch 5, also, is provided by disposing between the electrodes _{(11, 12),} and an "open" state of an electric field detection output device 10 prior to insertion in the electric field of the target 2, the At the end of use, it will be in the “closed” state. By putting the switch 5 in the "closed" state except during measurement, the virtual ground type current detector 2 and the LEDs 3 ₁ to 3 ₄ are prevented from being damaged by an overcurrent caused by an electric field that is not a target. do. This switch 5 is configured to be open/closed by the user, and is linked with the power switch.

The gripper (6) is configured as a flat plate of an insulator, and installed by placing the lower side of the electrode _(12), larger than the electrode _(12), protrudes outward.

When the electric field detection output device 10 having such a configuration is left still in the electric field formed by the _{electrodes 100 1} , 100 ₂ , as shown in FIG. 3 , for example, electric charges are transferred to the _{electrodes 1 1} , 1 _{2 .} Detects a current generated when is induced, and notifies the electric field strength by turning on the _{LEDs 3 1 to 3 4 .} Here, the electrodes 100 ₁ , 100 ₂ are each constituted by a flat plate, and two electrodes 100 ₁ , 100 ₂ are disposed so as to form a predetermined angle. An electric field in the direction of the arrow in the figure is formed between the _two electrodes 100 ₁ and 100 2 .

Next, the method of use and the operation of the electric field detection and output device 10 having such a configuration will be described.

In the case where the direction of the electric field of the measurement target is known, a method of measuring the electric field strength will be described. Here, as shown in FIG. 3, it is assumed that the electric field direction (arrow direction in the figure) formed by the _{electrodes 100 1} , 100 _{2 is known.}

First, by the user, the switch 5 of the electric field detection and output device 10 is in the "open" state. Then, the electric field detection and output device 10 is inserted into the electric field in a state in which the user holds the gripping unit 6 . At this time, the electric field detection output device 10 is, as shown in Figure 3, the electrode _{(11, 12),} is provided by arranging such that the normal to the electric field direction. At this time, there are the charge is an organic electrode _{(11, 12),} the electric current by the virtual ground type current detector (2) is detected, and the LED (3 ₁ ~3 ₄₎ is turned on in accordance with the magnitude of the current. Then, the electric field strength is confirmed by the number of lights, LED (3 ₁ ~3 ₄₎ by the user.

Next, the determination method of the electric field direction is demonstrated about the case where the electric field direction of a measurement object is unknown. Here, as shown in FIG. 3 , it is assumed that the direction of the electric field formed by the _{electrodes 100 1} , 100 _{2 is not known.}

First, the switch 5 of the electric field detection output device 10 is in the "open" state by the user, and the electric field detection output device 10 is inserted into the electric field in the state in which the grip part 6 is gripped. At this time, the electrode when the direction of the electric field detection output device 10, for example, by changing, as shown in Figs. 3 to _{5, LED (3 1 ~3 4} ) have a light most (1 _1, 1 ₂ ) is determined to be the direction orthogonal to the direction of the electric field.

Specifically, when the electric field detection output device 10 is oriented in the direction shown in FIG. 3 , the electric field lines that induce charges of different polarities are maximized on the _{electrodes 1 1} , 1 _{2 , so that the generated current is} It becomes the maximum, and four LEDs 3 _{1 -} 3 ₄ are turned on. When the electric field detection and output device 10 is set in the direction shown in FIG. 4 , _{the electric field lines that induce charges of different polarities on the electrodes 1 1} , 1 ₂ decrease with the inclination, so the generated current is the electric field. It becomes smaller than the case where the detection output device 10 is made into the direction shown in FIG. 3, and one LED3 ₁ turns on. If the electric field detection output device 10 in the direction shown in Figure 5, the electrodes _{(11, 12)} is not the charge is not organic, because this matches the direction of the electric field, which LED (3 ₁ ~3 ₄₎ also illuminates doesn't happen As described above, when the direction of the electric field detection output device 10 is set to the direction shown in FIG. 3 , the LEDs 3 ₁ to 3 ₄ are lit the most and it is known that the maximum electric field intensity is recognized. It is recognized that the direction orthogonal to the direction of the electrodes 1 ₁ , 1 _{2 is the direction of the electric field.} In addition, it can be recognized that the direction perpendicular to the direction of the electric field detection and output device 10 in FIG. 5 is an electric field direction.

If the electric field detection output device 10, an electrode as shown in Fig. 3 _{(11, 12)} installed in place so that the vertical with respect to the electric field direction, regarded as the electric field is a constant value according to target Since the electrode spacing d is sufficiently small compared to the distance between the electrodes, disturbance does not occur in the electric field formed by the _{electrodes 100 1} , 100 _{2 .} That is, invasiveness becomes minimal. As shown in Figure 4, the electrodes _{(11, 12)} full of a field that has, even when the installation is disposed so as to have a predetermined angle with respect to the electric field direction, is formed by an electrode (100 _1, 100 ₂₎ There is nothing to disturb At this time, the invasiveness becomes greater than when the electric field detection and output device 10 is oriented in the direction shown in FIG. 3 .

As described above, the electric field detection output device 10 by simply inserting in the electric field, the electrodes _{(11, 12),} a current detected by the virtual ground type current detector (2), LED (3 ₁ occurred in ~ Since the electric field strength can be measured and notified in real time by the number of lights of _{3 4 ), it is excellent in simplicity and quick reporting. In addition, in the space formed by placing the electrodes 1 1} and 1 ₂ composed of a flat plate to face each other, the virtual ground type current detector 2, the LEDs 3 ₁ to 3 ₄ , the battery 4, Since the switch 5 is accommodated, even when the electric field detection and output device 10 is inserted into the electric field, the electric field to be measured is not disturbed, and it is excellent in precision and non-invasiveness. For this reason, the electrodes 1 ₁ , 1 ₂ can be downsized to a size that can accommodate the virtual ground type current detector 2 , the LEDs 3 ₁ to 3 _{4 , the battery 4 , and the switch 5 .} can That is, the electric field detection output device 10 can be miniaturized to a size that can be inserted into a pocket, mounted on clothes, always portable, or mounted on a fingertip.

In addition, since _{the electric field intensity proportional to the detected current can be recognized by the number of lights of the LEDs 3 1} to 3 ₄ , the electric field can be measured and displayed with high precision, so that the electric field intensity can be grasped with high precision. can

In addition, the direction of the electric field can be recognized by changing the direction of the electric field detection output device 10 in the target electric field, measuring the electric field intensity, and comparing the number of lights of the _{LEDs 3 1} to 3 _{4 .}

Furthermore, since the electric field detection and output device 10 can be put in and out of the electric field while the holding part 6 made of the insulator of low dielectric constant is gripped and can be measured, it is excellent in simplicity and non-invasiveness.

The electric field detection and output device 10 having such an effect can generate an electric field, measure the electric field strength in an apparatus using the electric field, or grasp the electric field distribution. Specifically, for example, it is possible to measure the electric field strength or to grasp the electric field distribution in treatment, life, or work under the use of a medical device that generates a high electric field or a treatment device including a potential therapy device. there is. Further, it is possible to measure the electric field strength in a plastic molded article or an object containing powder excessively charged with static electricity, or a user's human body, or to grasp the electric field distribution. At this time, as shown in Fig. 6, according to the measured electric field strength, the possibility of electric shock is set to "danger level", "warning level", etc., and when the electric field strength is greater than a predetermined value, an alarm sound is output to notify You can do it.

In particular, by detecting the state in which the user's human body is excessively charged with static electricity, it becomes possible to grasp the danger of a lightning strike or electrostatic shock tube.

Further, since the electric field detection and output device 10 is of a card type, it can be inserted into a user's pocket or worn on clothes, so that it can be easily carried. For this reason, the electric field detection and output device 10 can always be carried, and an electric field can always be easily measured. That is, since the electric field can be easily measured at any time, even in treatment, life, or work under the use of, for example, a medical device or treatment device that generates a high electric field, convenience is further improved.

(Embodiment 6)

11 is a schematic structural block diagram of Embodiment 6 of the present invention. The electric field adjustment system 70 is divided roughly, and is comprised from the electric potential therapy apparatus 71 and the electric field detection output apparatus 72. As shown in FIG.

The potential treatment device 71 further includes a receiving means 711 and a voltage adjusting means (adjusting means) 712 in the conventional potential therapy device 200 .

The receiving means 711 is a device for receiving a signal by a communication method such as infrared, sound wave, radio wave, or wired communication, and transferring the signal to the voltage adjusting means 712 . The receiving means 711 receives the signal transmitted from the electric field detection output device 72 , converts the content (current value) into an electric signal, and transfers it to the voltage adjusting means 712 .

The voltage adjusting means 712 adjusts the voltage generated by the voltage generator 2004 based on the current value received from the receiving means 711 .

The voltage adjusting means 712 has a storage function, an arithmetic function, an input function, and a control function.

The memory function consists of a storage device such as a flash memory, and in this Embodiment 6, in particular, a predetermined electric field value, information on the physique and body shape of the to-be-treated person in the past (height, sitting height, weight, obesity, etc.); The applied voltage intensity (adjusted value) at that time is stored.

In addition, after the treatment is performed, information on the physique and body shape of the subject to be treated and the adjusted voltage intensity are stored in association with each other.

The input function is an information processing device such as a notebook computer or a portable terminal such as a smart phone, and is for inputting information on the physique and body shape of the subject to be treated with respect to the storage function before the start of treatment.

The arithmetic function is a device composed of a central processing unit (CPU). _{The arithmetic function calculates the electric field strength, that is, the rms} field strength value E rms or the electric field strength E(t), based on Equation 1 or Equation 2, from the current value received from the receiving means 711 . Then, the electric field intensity is compared with a predetermined electric field value stored in the storage function to determine whether there is a difference. Then, when there is a difference, a voltage adjustment instruction is given to the control function so as to adjust the voltage so as to eliminate the difference. Here, eliminating the difference is not limited to the fact that the two are completely identical, but includes falling within the range of the error determined in advance and stored in the memory function. In addition, before the start of treatment, it is searched for whether the memory function of the to-be-treated person having a physique/body shape that approximates or coincides with the inputted physique/body type is in the memory function. With reference to the control function, a voltage adjustment instruction is indicated so as to adjust to the voltage intensity.

The control function is a circuit that controls the voltage generator 2004 based on a voltage adjustment instruction transferred from the arithmetic function. Here, when there is no voltage adjustment instruction from the arithmetic function (for example, the memory function does not have a memory that approximates or matches the physique/body type of the subject), a voltage generator ( 2004) is controlled.

The voltage adjusting means 712 repeats the above process until the difference between the electric field strength and the predetermined electric field value is eliminated.

Next, the electric field detection and output device 72 will be described.

The electric field detection output device 72 according to the sixth embodiment differs from the electric field detection output device 10 according to the first embodiment in that the output means is not the LEDs 3 ₁ to 3 ₄ , but a transmitter (transmission means) 721 . , the same reference numerals are attached to the other components, and description thereof is omitted.

The transmitter 721 is a site for transmitting a signal to the receiving means 711 by a communication method such as infrared, sound wave, radio wave, or wired communication, and is composed of a function or device that transmits a signal, such as an infrared light emitting unit. .

That is, when the electric field detection and output device 72 detects an electric field, the transmitter 721 transmits a different signal to the receiver 711 according to the strength of the electric field.

Next, the effect|action of this Embodiment 6 and the electric field adjustment method are demonstrated based on FIG. 12 and FIG.

With the switch 5 of the electric field detection output device 72 in the open state, the electric field detection output is output at a position of 0 to 10 cm from each part of the body of the subject P, such as the head, arm, and chest. The device 72 is left still (step S1).

Next, the information (height, sitting height, body weight, obesity, etc.) of the to-be-treated subject P is stored in the memory function by the input function of the electric potential treatment device 71 (step S2).

The potential therapy device 200 is seated on the subject P, the potential therapy device 71 is started, and a voltage is applied between the electrodes by the voltage generator 2004 (step S3).

The arithmetic function of the voltage adjusting means 712 of the potential treatment device 71 searches for whether there is data of the physique and body that approximates or matches the information of the physique and body of the subject P input to the storage function, (Step S4), if present, a voltage adjustment instruction is given to the control function to adjust the voltage to the value of the voltage intensity stored in the storage function (Step S5). On the other hand, if it does not exist, a voltage adjustment instruction is given so as to apply a set voltage (step S6).

In steps S5 and S6, the voltage generator 2004 receiving the voltage adjustment instruction applies a voltage according to the instruction by adjusting the voltage.

The electric field detection and output device 72 detects the electric field applied to the body of the subject P.

A signal according to the magnitude of the current is transmitted from the transmitter 721 of the electric field detection and output device 72 .

The electric potential therapy device 71 receives a signal by the receiving means 711 (step S7), and measures the electric field strength by the arithmetic function of the voltage adjusting means 712 (step S8). Then, by the control function of the voltage adjusting means 712, it is determined whether the electric field strength differs from the predetermined electric field value stored in the storage function of the voltage adjusting means 712 (step S9), and the difference is If there is, the voltage generated by the voltage generator 2004 is adjusted so that it disappears (the same or within a predetermined error range) (step S10).

When the electric field strength does not differ from the predetermined electric field value by adjusting the voltage, the voltage adjusting means 712 stops adjusting the voltage, and the voltage generator 2004 applies the adjusted voltage.

When treatment is performed for a desired period of time, the potential therapy device 71 is stopped (steps S11 and S12), and the switch 5 of the electric field detection output device 72 is put into a closed state. At this time, information on the physique/body type of the subject to be treated and the adjusted voltage intensity are stored in association with the memory function (step S13).

According to the sixth embodiment, the electric field applied to the human body can always be maintained at a predetermined strength regardless of the difference in the physique and body shape of the subject P. It is possible to obtain a stable therapeutic effect.

By increasing the number of LEDs 3, the electric field strength can be notified more accurately. In addition, it goes without saying that the electric field intensity may be output recognizable by the brightness|luminance of one LED3.

The output means is not limited to the _{LEDs 3 1 to 3 4} and the transmitter 721, but includes a digital display device capable of outputting current values and electric field strength as it is, audio output means including a speaker, and a vibrator.

Also, a back electrode _{(11, 12)} has the shape of, the shape that is not limited to square, to maintain a non-invasive, and even other shapes such as a circle. In addition, when a plurality of electrodes 1 are arranged and provided in an array shape as shown in Embodiment 5, a shape capable of shortening the distance from the electrode 1 of the unit in contact, for example, a star If it is a shape which has the same convex part as a shape, the interference between units will become strong and the measurement precision will fall.

Further, in the sixth embodiment, the adjusting means is not limited to the voltage adjusting means 712 , for example, it is an electrode adjusting means for adjusting the position and angle of the upper electrode 2001 to an appropriate state. The strength of the electric field applied to the body of the subject P may be changed.

As a means for adjusting the electric field strength by changing the position of the upper electrode 2001, for example, the upper electrode 2001 and the backrest of the potential therapy device 200 are separated, and the position of the upper electrode 2001 is adjusted to the upper and lower It has a movement function that makes it variable in the direction. Then, by attaching the electric field detection output device 72 to the upper electrode 2001 and moving the upper electrode 2001 up and down to adjust the distance between the electric field detection output device 72 and the subject P, the electric field The intensity can be adjusted. Here, the movement of the upper electrode 2001 can be either automatic or manual. However, in the case of automatic movement, the position is controlled in conjunction with the calculation function, and the position of the upper electrode 2001 after the change is set to the target ( Efficiency of electric field adjustment becomes possible by storing in the storage means in association with information of the physique and body shape of P) and the voltage after adjustment.

Further, as means for adjusting the electric field strength by changing the angle of the upper electrode 2001, for example, the electric field detection output device 71 is mounted on the upper electrode 2001 in the same manner as the position change, and the mounting pedestal By providing a tilt function to the body, the intensity of the electric field can be adjusted by adjusting the inclination (angle) of the electric field detection and output device 71 with respect to the subject P. Also in this case, the tilt function controls the angle in conjunction with the calculation function, and correlates the changed angle of the upper electrode 2001 with information on the physique and body shape of the subject P and the voltage after adjustment to the storage means. By memorizing, the efficiency of electric field adjustment becomes possible. Moreover, in order to implement|achieve a movement function and a tilt function, a small motor, hydraulic pressure, air pressure, etc. are conceivable. Moreover, you may use together the method of adjusting the position and angle of these electrodes, and the voltage adjustment means 712.

In addition, in the potential therapy device 71 , the receiving means 711 and the adjusting means 712 are not provided, that is, as the conventional potential therapy device 200 , the electric field detection and output device 72 is applied to the electric field as described above. A digital display device capable of outputting the intensity as it is may be provided, the electric field intensity may be grasped, and the voltage of the electric potential therapy device 200 may be adjusted so that the electric field strength may become a predetermined electric field value by a human hand.
