Example Embodiment

[0032] The present invention also provides a method for preparing a flexible physiological dry electrode, which includes the following steps:

[0033] (1) Stack the connecting buckle with a piece of foil and put it in a container;

[0034] In this example, the container is a petri dish. In practical applications, the container can be any of a petri dish, a beaker, and the like. The foil used in the present invention can be any material, and the thickness of the foil can be determined according to the thickness of the electrode. Preferably, the diameter of the foil is 0.5 cm-3 cm and the thickness is 1 mm-0.5 cm.

[0035] (2) Pour the polydimethylsiloxane into the container, fill the container and put it into the oven to cure the polydimethylsiloxane.

[0036] (3) After curing, take the polydimethylsiloxane connected with the connecting buckle and the foil out of the container, remove the foil, and form a groove on the cured dimethylsiloxane.

[0037] (4) Mix polydimethylsiloxane with c...

Example Embodiment

[0043] Example one

[0044] Such as Figure 2a to Figure 2d As shown, the foil 3 and the connecting buckle 2 are placed in a petri dish 4, injected with polydimethylsiloxane 5, and placed in an oven to cure at 70°C for 2 hours. After curing, remove the petri dish 3, turn the polydimethylsiloxane connection foil 3 and the connection buckle 2 over, remove the foil 3, and form a groove on the cured polydimethylsiloxane, and then The polydimethylsiloxane 6 doped with carbon nanotubes is cast into the groove 7 and cured in an oven at 70° C. for 2 hours. Finally, the polydimethylsiloxane 5 is removed to obtain the flexible physiological dry electrode of the present invention, such as figure 1 Shown.

[0045] The actual application requirements of this embodiment are as shown in Table 1, which is a set of preferred design parameters of the flexible physiological dry electrode of the present invention.

Abstract

The invention relates to a flexible physiological dry electrode and a preparation method of the flexible physiological dry electrode. The flexible physiological dry electrode comprises a conductive poly-dimethyl siloxane electrode and a connection buckle; the conductive poly-dimethyl siloxane electrode is used for contacting the skin; the connection buckle is used for leading out a lead to a measurement circuit, and the connection buckle is partially embedded inside the conductive poly-dimethyl siloxane electrode. The conductive poly-dimethyl siloxane electrode has the advantages of being high in collecting quality, strong in reliability, safe and comfortable, low in cost and wide in application range.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to a flexible physiological dry electrode and a preparation method thereof. Background technique [0002] In recent years, as the problem of population aging has become increasingly prominent, the development of medical care and home care systems has become an urgent need. The traditional medical methods for the treatment of diseases are mostly after the onset of the disease, which cannot be well prevented and real-time diagnosis and treatment. However, the new technology represented by the wireless body area network can analyze and process the existing physiological parameters in real time, thereby Provide early warning before the onset, or provide a timely emergency plan when the onset occurs. Physiological electrodes play a vital role in wireless body area network systems. Physiological electrodes for WBAN can be used to measure physiological electrical signals of the human body, suc...
