preparation example Construction

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

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

[0034] In this example, the container is a petri dish, and in practical application, the container may be any one 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 0.5cm-3cm, and the thickness is 1mm-0.5cm.

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

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

[0037] (4) Mix polydimethylsil...

Embodiment 1

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

[0045] The dimensions required for the practical application of this embodiment are shown in Table 1, which is a set of optimal 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...
