A Robotic Electrochemical Biosensor Based on Kinetic Electronics Technique

Abstract

The integration of biosensing technology and soft robots can improve the diagnostic and therapeutic functions of bionic machines, and provide wearable devices with flexible, low-invasive, real-time monitoring biosensing functions. Here, a robotic electrochemical biosensor based on kinetic electronics technique was developed. The film robot is composed of a bimorph actuator layer and a biosensing function layer. The sensor function layer adopts sputtering technology to form a gold electrode, and is processed to form a Nafion-coated glucose oxidase electrode. The film robot could be used as a kinetic printed circuit for probe chips for biological and chemical experiments, and can realize bending action under an applied voltage of 5 V.
