Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only and are not to be construed as limiting the present invention, and all other embodiments that can be made by one skilled in the art without inventive effort based on the embodiments of the present invention shall fall within the scope of protection of the present invention.
The application provides a stimulation current control method which is mainly applied to an intelligent wearing device to intelligently control and adjust stimulation current applied to forehead skin or muscle skin of the intelligent wearing device. In the application, the execution terminal of the stimulation current control method can be an intelligent wearing device or a stimulation current control device, and the intelligent wearing device can be products such as an electroencephalogram head ring, an electroencephalogram cap, an electroencephalogram head cover and an intelligent sleeping eye shield. It should be noted that the intelligent wearable device in the present application includes an electromyographic device, the electromyographic device also obtains an electromyographic signal by contacting the skin of the upper limb or the lower limb through an electrode, and similarly, when the output voltage of the electromyographic device is higher than a preset threshold value, the problem of the skin pricking by the electrical stimulation also occurs, so the electromyographic device is also applicable to the steps in all the embodiments, and only difference is that the control and adjustment of the stimulation current applied to the forehead skin or the control and adjustment of the stimulation current applied to the muscle skin. The myoelectric device can be an intelligent bionic hand, an intelligent artificial leg, a myoelectric arm ring, an intelligent hand ring and the like.
Referring to fig. 1, in one embodiment, a stimulation current control method includes:
s101, detecting output voltage of the intelligent wearing device in real time, and judging the wearing state of the intelligent wearing device according to the change condition of the output voltage;
and S102, when the intelligent wearing device is judged to be in the abnormal wearing state, controlling the current value of the stimulating current of the intelligent wearing device to be reduced to be not higher than a preset first current value.
In this embodiment, the user is when wearing intelligence and wearing the device and help sleeping, the inboard brain electricity electrode that sets up of device can contact with forehead skin for intelligence is worn, carry out little electric stimulation through brain electricity electrode output invariable stimulation current, under the normal circumstances of wearing, this invariable stimulation current helps amazing brain secretion sleep transmitter and promotes sleep, but in the use, because unusual wearing for example the head ring slightly moves, change the sleeping position or take off in the twinkling of an eye, can make electrode and skin contact not good and the tingling sensation that leads to the fact user's forehead, this embodiment prevents that the electrode from causing the tingling sensation through control regulation stimulation current promptly to user's forehead.
In step S101, when the intelligent wearable device is normally worn on the forehead of the user, the electroencephalogram electrode is in good contact with the skin of the forehead, and at this time, the contact position between the electroencephalogram electrode and the skin is equivalent to a resistance, the larger the contact area is, the smaller the resistance is, and conversely, the smaller the contact area is, the larger the resistance is. Then, when the electroencephalogram electrode is known to be in good contact with forehead skin, the contact area between the electroencephalogram electrode and the skin is the largest, the contact area can be reduced when a user changes sleeping postures or moves the intelligent wearing device, and under the condition that the current is constant, the larger the resistance is, the larger the voltage is, and the intelligent wearing device can judge the wearing state of the intelligent wearing device by detecting the output voltage.
Optionally, when the user wears the intelligence and wears the device and select to help the dormancy mode, the intelligence is worn the device and can be through the contact condition of pressure sensor response brain electrode and user forehead skin, if brain electrode is not good with skin contact, then when the user clicks and begins to help the dormancy, suggestion intelligence is worn the device and is located the abnormal wearing state, adjusts the wearing state well until the user, just allows the intelligence to wear the device and begins to help the dormancy.
The mode of the user selecting the sleep-aiding mode of the intelligent wearing device can be that the sleep-aiding mode is selected on an application program of an intelligent terminal (such as a mobile phone, an intelligent watch and a computer) which is in wireless connection with the intelligent wearing device, or a sleep-aiding button on the intelligent wearing device is directly clicked. If the sleep-aiding mode is selected on the application program, when the intelligent wearing device is in an abnormal wearing state and a user clicks a sleep-aiding button, the application program pops up a prompt box to prompt the user to adjust the intelligent wearing device; if adopt the mode of directly clicking help dormancy button on the device is worn to intelligence, then wear the device when intelligence and be in the abnormal state of wearing, the device can be worn through voice prompt user adjustment intelligence to the intelligence and wear the device until wearing normally.
Optionally, an output plate is arranged on the intelligent wearing device, and the output plate adjusts output voltage in real time according to the change of the contact area between the electroencephalogram electrode and the forehead skin of the user.
Like this, wear the device at intelligence and begin to help before sleeping, wear the state of wearing of device to intelligence and detect, can prevent effectively that when helping sleep to begin, because the wearing mode that the user is irregular leads to the user to produce the tingling sensation to improve user's the experience of helping sleep.
In an optional implementation manner of this embodiment, the step of determining the wearing state of the intelligent wearing device according to the variation condition of the output voltage includes: when the output voltage is detected to exceed the voltage threshold, the intelligent wearing device is judged to be in an abnormal wearing state.
Specifically, in the sleeping process of a user, the situation that the contact surface between the electrode and the skin changes due to the change of the sleeping posture is inevitably generated, so that in the actual use process, the output voltage is constantly changed, aiming at the situation, a voltage threshold can be set for the output voltage, when the output voltage floats in the voltage threshold, the resistance change is small, the current density in the unit area of the electrode in contact with the skin is not enough to generate electric stimulation, but when the output voltage exceeds the voltage threshold, the contact area between the electroencephalogram electrode and the skin is reduced, the resistance is increased, and the intelligent wearing device is determined to be in the abnormal wearing state.
In an optional implementation manner, the step of determining the wearing state of the intelligent wearing device according to the variation of the output voltage further includes: when the output voltage is detected not to exceed the voltage threshold, judging that the intelligent wearing device is in a normal wearing state; or when the output voltage is detected not to exceed the voltage threshold and the auxiliary detection feedback is normal, judging that the intelligent wearing device is in a normal wearing state; wherein, supplementary detection includes that the device is worn to intelligence infrared induction detects, forced induction detects, at least one among the EEG signal detects.
It should be noted that, when the wearing state of the intelligent wearing device is determined, since the present embodiment aims to avoid the user from receiving electrical stimulation, when the output voltage exceeds the preset threshold, it may be determined that the intelligent wearing device is in an abnormal wearing state, and when it is determined that the intelligent wearing device is recovered to the normal wearing state, it may not be accurate simply by detecting whether the output voltage falls within the preset threshold, and therefore, it is also necessary to perform auxiliary detection in combination with other manners to improve the accuracy of detection.
Specifically, in the process of detecting the wearing state of the intelligent wearing device, infrared induction detection, pressure induction detection and electroencephalogram signal detection can be combined besides the output voltage of detecting the head loop of the head bag. It should be noted that the smart wearable device is also equipped with an infrared sensor and a pressure sensor, respectively. The infrared sensor can detect the contact state of the electroencephalogram electrode and the skin through the infrared thermal imaging function, the pressure sensor is connected with the electroencephalogram electrode, and whether the electroencephalogram electrode is in contact with the forehead skin of a user or not is sensed through pressure. In addition, the Electroencephalogram electrode can be an EEG (Electroencephalogram) electrode, electroencephalogram signals of the user are collected through the EEG electrode, if the Electroencephalogram signals exist, the Electroencephalogram electrode is in normal contact with the forehead skin of the user, and if the EEG signals do not exist, the electrode is in abnormal contact with the forehead skin of the user. It should be noted that no matter the detection output voltage is combined with infrared induction, pressure induction or electroencephalogram signal, the accuracy of the detection output voltage is improved, so that the detection current is timely adjusted to the original stimulation current under the condition that the intelligent wearing device is restored to normal wearing, and the sleep-aiding experience of a user is improved.
In step S102, when it is determined that the smart wearable device is in the abnormal wearable state, the output board is controlled to decrease the output current so that the current value of the stimulation current applied to the head by the electrodes of the smart wearable device is decreased to be not higher than the preset first current value. The first current value is a current threshold (recorded as a protection current value) which ensures that the electroencephalogram electrode cannot generate a pricking feeling on a skin contact part, and the protection current value can be a numerical value (namely a preset value) which is already written into a program when a protection mechanism is set, and can also be a current value which is automatically generated by the intelligent wearing device and cannot generate the pricking feeling on the premise of ensuring a sleep-assisting effect.
Optionally, the first current value may be a protection current value that does not generate a tingling sensation and is determined by experimental data of a large number of human skin adaptation degrees to electrical stimulation in a design process of a protection mechanism of the intelligent wearable device.
Optionally, in the sleep-assisting process, under the condition of normal wearing, the intelligent wearing device may calculate a contact area between the electrode and the skin through the infrared sensor or the pressure sensor, calculate a current density of the constant stimulation current in a unit area where the electroencephalogram electrode is in contact with the skin, and calculate an average value of the current density under the normal wearing condition, when the intelligent wearing device is in the abnormal wearing state, calculate a first current value based on the obtained average value of the current density in combination with the contact area between the electroencephalogram electrode and the forehead skin of the user under the current abnormal wearing state, and adjust the stimulation current of the intelligent wearing device to be not more than the first current value.
Like this, under the abnormal wearing state, will carry out the stimulation current of the invariant of electro photoluminescence to the user and descend to not being higher than the first current value of predetermineeing, under the prerequisite of avoiding producing the tingling sensation to the user, guaranteed promptly to help the sleep effect, can improve user's the experience of helping sleep again.
In an optional implementation manner, on the basis of the foregoing embodiment, after the step of detecting the output voltage of the intelligent wearable device in real time and determining the wearing state of the intelligent wearable device according to the variation of the output voltage, the method further includes: and when the intelligent wearing device is judged to be recovered to the normal wearing state, the stimulation current of the intelligent wearing device is controlled to be increased to a preset standard current value.
In this embodiment, the standard current value is a constant current value of the intelligent wearing device in a normal wearing state, after the current value of the stimulation current is reduced to the first current value by the intelligent wearing device, the wearing state of the intelligent wearing device needs to be continuously detected, and if the wearing state of the intelligent wearing device is recovered to the normal state, the stimulation current of the intelligent wearing device is increased to a preset standard current value, so as to ensure the sleep-aiding effect of the intelligent wearing device.
In an embodiment, as shown in fig. 2, on the basis of the embodiment shown in fig. 1, the stimulation current control method further includes:
and step 203, determining a voltage threshold according to the regulated stimulating current gear.
Specifically, in practical application, the electric stimulation is applied to the forehead skin of a user through the current to achieve the sleep-assisting effect, the sleep-assisting effect is a very objective thing, a user group is often easily influenced by the age, the skin of the user in different age groups is different in the sensitivity degree of the electric stimulation, and the sleep-assisting experience can be influenced by the skin condition of the user in the same age group. In the embodiment, the intelligent wearing device can preprocess the stimulation current when the user is electrically stimulated, and automatically adjusts the current stimulation current gear according to the preprocessing result, wherein the preprocessing comprises the steps of detecting the electroencephalogram signals of the user when the user is electrically stimulated according to the electroencephalogram signal detection device of the electroencephalogram electrode, and determining the sensitivity degree of the forehead skin of the user to the electrical stimulation according to the electroencephalogram signals, the higher the intensity of the electroencephalogram signals is, the higher the sensitivity degree to the electrical stimulation is, and the lower the intensity of the electroencephalogram signals is, the lower the sensitivity degree to the electrical stimulation is. Each stimulating current gear in the intelligent wearing device corresponds to a constant stimulating current, output voltage can be determined according to the constant stimulating current after the gears are determined, when the strength of the electroencephalogram signals detected after the stimulating current gears are determined does not accord with standard strength, the intelligent wearing device can automatically adjust the current stimulating current gears, and the voltage threshold of the output voltage is determined according to the adjusted stimulating current gears. Therefore, the stimulation current of the intelligent wearing device is not fixed, and the sleep-assisting effect of the intelligent wearing device on the user can be effectively improved according to the proper current gear of the wearing user before the electrical stimulation is started.
Optionally, the device is worn to intelligence when opening and helps dormancy mode, and the user can be according to the current stimulation specification that the device was worn to intelligence selection own most comfortable electric current gear, and the device is worn to intelligence then can confirm corresponding output voltage according to the electric current gear that the user selected, and this output voltage, in whole help dormancy in-process, if the contact surface of brain electricity electrode and user's forehead skin does not take place great change, output voltage then can not change to the electric current of guaranteeing this electric current gear output is the constant current. Optionally, the device is worn to intelligence still is provided with the electro photoluminescence protect function, and this function considers that the user is experiencing the sleep-aiding function of the device is worn to intelligence for the first time, can't accurately understand self to the adaptation degree of electro photoluminescence, consequently, when the user selects the electric current gear to begin to help sleeping, the device is worn to intelligence just can output a very low electric current, then increases the electric current size step by step, until increasing the electric current size to the stimulation electric current of the standard of this gear. In the process, if the skin of the user generates slight pain due to electric stimulation, the current gear can be adjusted at any time, and the skin of the user is ensured to be in a comfortable state at any time.
Optionally, the intelligent wearable device may also adjust the current level according to the skin stress response. For example, when the elderly use the smart wearable device, even though the forehead has experienced a significant tingling sensation due to the mobility inconvenience of the elderly, the current level cannot be adjusted through the corresponding application program or the button of the smart wearable device. Therefore, in the embodiment, it can also be determined whether the forehead of the user is subjected to the tingling sensation generated by the electrical stimulation through the stress response of the forehead skin received by the electrodes of the intelligent wearable device, wherein the skin stress response includes, but is not limited to, pore contraction and the like.
Optionally, the intelligent wearable device can also detect the electromyographic signals of the user by contacting the skin of the upper limb or the lower limb through the electrodes; adjusting the current stimulating current gear according to the detected electromyographic signals; and determining a voltage threshold according to the regulated stimulating current gear.
Like this, this embodiment sets up the electric current gear according to the adaptation degree of user to electro photoluminescence, wears the device at the intelligence and begins to help when sleeping, through electro photoluminescence protect function and electrode real-time supervision skin stress, improves user's the experience of helping sleeping.
