Abstract

This letter presents the optimum value of skin-electrode capacitance for a capacitive electromyography (CEMG) biosensor design. Skin-electrode capacitance is proved to be an important variable when defining the input characteristic of a capacitive biosensor by an electrical model of skin-electrode interface. The experimental results show that a CEMG biosensor with the skin-electrode capacitance range of between 255 and 340 pF yields the best performance, low noise, and is small in size.
