Description

Induction electrode

The present invention relates to a technique for an electrode, and more particularly to a soft sensing electrode.

According to the evolution of medical technology, many human body passwords are cracked, and physiological signals can be easily detected to allow doctors to further understand the patient's physical condition, such as detecting ECG output ECG, according to the heartbeat cycle frequency. Predict whether the patient's heart is healthy; detect the EMG output EMG, can predict whether the patient's muscles, nervous system or even the cerebellum have problems according to the waveform; and detect the brain wave signal is to measure the current of the cerebral cortex, by Physiological changes in the brain determine the patient's consciousness, mood, etc., or the tracking of patients with coma, stroke, epilepsy, encephalitis, and other brain diseases.

At present, the electrodes for detecting physiological signals are mostly wet electrodes, and the electrode sheets are adhered and adsorbed on the body, and then the metal clips are clamped on the electrode sheets to detect physiological signals, such as the adhesive electrodes used for checking the electrocardiogram; However, if you want to detect brain waves, it is much more troublesome. Because the scalp is covered with hair, the hair is different from the body surface. It is thick and dense. It is difficult to stick the electrode on the scalp, and it is not easy to conduct electricity through the hair. If the hair is not shaved, it is necessary to apply conductive adhesive on the electrode sheet to help conduct electricity. In addition to the long preparation time and possible damage to the scalp, the conductive glue will dry out in half an hour, so the conductive adhesive needs to be added every half hour. It often makes the tester full of glue; there is also a dry electrode, which is a cube with a length and width of 1.5 cm. It does not need conductive glue to help conduct electricity, but it is still affected by hair interference when measuring brain waves. Test results.

In view of the above, the present invention has been directed to the absence of the above-mentioned prior art, and proposes an inductive electrode to effectively overcome the above problems.

SUMMARY OF THE INVENTION The main object of the present invention is to provide a sensing electrode which uses a soft needle electrode to contact the skin, such as the scalp, and a soft soft probe for arranging the hair without shaving or applying conductive glue. It can directly touch the scalp to sense brain waves, and its soft material also has a good protective effect on the scalp.

Another object of the present invention is to provide an induction electrode in which the base and the soft probe are electrically conductive, and the soft probe is bendable to increase the contact area with the skin, and not only the tip of the probe can sense physiological signals.

To achieve the above object, the present invention provides a sensing electrode comprising a base and a plurality of soft probes, the soft probe standing on one side of the base, sensing at least one physiological signal and transmitting through the base. When the sensing electrode is close to the skin for sensing, the material characteristics of the soft probe can be used to separate the hair and the probe is bent into contact with the skin to sense the physiological signal, thereby preventing the hair barrier from affecting the sensing effect.

The purpose, technical content, features and effects achieved by the present invention will be more readily understood by the detailed description of the embodiments.

The invention is a sensing electrode which can be applied to a brain wave cap, which detects a brain wave signal by an induction electrode or is attached to a chest when detecting an electrocardiogram signal.

Please refer to FIG. 1 and FIG. 2 , which are respectively a perspective view and a top view of an embodiment of the sensing electrode of the present invention. The sensing electrode 10 of the present invention comprises a base 12 and a plurality of soft probes 14 , and the base 12 can be any shape. In this embodiment, the base 12 is circular; the soft probe 14 is erected on one side of the base 12, sensing at least one physiological signal and transmitting through the base 12, the soft probe The number, length, and thickness of the needle 14 are not limited. In this embodiment, there are five soft probes 14, each of which has the same length and thickness.

The factors affecting the rate of the probe for the physiological signal include the contact area, the impedance and the conductivity. The base 12 and the soft probe 14 are both soft and conductive materials, and the material thereof can be, for example, a silicone glass mixed with a low impedance; The base 12 and the soft probe 14 are integrally molded, and the manufacturing method is a hot press molding or an injection molding method.

In the embodiment of FIG. 1, the soft probe 14 is perpendicular to the base 12, and the soft probe 14 is a straight strip; and FIG. 3 is another embodiment of the sensing electrode 10 of the present invention, which is soft in this embodiment. The tip end of the probe 14 is outwardly curved and expanded to facilitate the discharge of the hair.

When the sensing electrode of the present invention is applied to the skin for sensing, a plurality of sensing electrodes may be mounted on a brain wave cap for measuring brain waves, or an instrument for measuring other physiological signals, and the soft probe contacts the skin. The soft material properties cause the tip of the soft probe to bend due to pressure, thereby arranging the surrounding hair and sensing physiological signals such as electrocardiogram, brain wave signal or myoelectric signal on the skin surface. Avoid hair barriers affecting the sensing effect and transmit a complete and clear signal to the measuring instrument. In addition, the soft material of the soft probe also has a good protective effect on the scalp.

In summary, the present invention provides a sensing electrode that utilizes a soft, electrically conductive soft probe in combination with an equally flexible and electrically conductive base that can be used to vent the hair without the need to apply conductive glue or shave the hair. The skin, and the flexible soft probe increases the contact area with the skin and increases the chance of receiving physiological signals.

The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Therefore, any changes or modifications of the features and spirits of the present invention should be included in the scope of the present invention.
