A Novel Bioelectrode Design with an OTFT Switch for Dynamic Discharging

Abstract

As an important interface between biological tissues and flexible electronics, bioelectrodes suffered from charge accumulation during long-time sensing or stimulation, which significantly affects electrode lifespan and signal transmission. This paper introduces an OTFT switch paralleled to the bioelectrode to discharge electrodes and maintain their voltage, which have the potential to prolong the lifespan and stability of bioelectrodes, while maintaining their flexibility.
