Nano-clay-Based Flexible Bio-electrode for Neural Sensing Applications
Implantable bioelectrodes play an essential role in preventing muscle atrophy when used in systems that bridge the gap between injured neurons and muscles in peripheral nerve injuries. They are used to record neural electrical activity and produce and stimulate muscles. The prime objective of this study is to fabricate flexible, low cost and biocompatible electrodes using silicone polymer and nano-clay. This flexible electrode should help to solve some of the drawbacks of using metal electrodes, such as mechanical mismatch and immunological reactions. In this study, two batches of bioelectrode samples were fabricated using different weight proportions of silicone polymer, nano-clay, and glycerol. Batch one was fabricated with a mass ratio of 1:5 of nano-clay:silicone and a specific mass of glycerol ranging from 0.0558 g to 0.15 g while batch two was fabricated with a mass ratio of 1:10 of glycerol: silicone and a specific mass of nano-clay ranging from 0.2 g to 0.4 g. Then the samples were evaluated for their electrochemical characteristics such as impedance at 1 kHz, bulk impedance, and conductivity. The result of the best fabricated sample showed an impedance of 70.98 kΩ at 1 kHz and a bulk impedance of 0.297 kΩ with high conductivity of 10.49 × 10−4 S/cm which exhibited promising electrical properties.
