2、 The limitations of traditional wet electrodes and the rise of flexible dry electrodes

At present, silver/silver chloride (Ag/AgCl) wet electrodes are widely used in clinical practice to collect bioelectric signals. However, the wet electrode relies on the conductive gel as the skin coupling medium, which has three congenital defects:Conductive adhesive is prone to drying up over time, affecting signal quality;Gel ingredients irritate skinNot suitable for long-term continuous monitoring;Poor breathabilityIt can easily cause skin discomfort.

In this context,Flexible dry electrodeBecoming a recognized technological direction in the industry. The dry electrode does not need conductive gel, and can directly contact with the skin to collect signals, withNon irritating, can be worn for a long time, stable signalWaiting for core advantages. However, dry electrodes impose extremely stringent requirements on the biocompatibility, flexibility, conductivity, and long-term stability of materials.

3、 LCP: Ideal Base Material for Bioelectrodes

Liquid crystal polymer (LCP) films are becoming an ideal choice for bio electrode substrates due to their unique material properties.

LCP hasExtremely low water absorption rate(<0.1%), able to maintain stable electrical performance in humid environments and long-term use. Meanwhile, lcpExcellent biocompatibilityThe cytotoxicity test shows that the cell survival rate is>95%, and long-term wearing will not cause skin irritation or allergic reactions. This feature makes it particularly suitable for scenarios that require high biological safety, such as flexible electrodes for brain computer interfaces and implantable neural electrodes.
