Sensor interface circuit for artificial skin sensor using CNFET

For future robotic and prosthetic applications, it is essential to develop a robust and low power artificial skin for detecting the environment through touch. Thus, a sensor interface circuit for the artificial skin also has to be developed to detect the sensor signals and convert them into digital bits. In this paper, a new sensor interface circuit using a 32 nm CNFET technology for an artificial skin sensor is proposed. The artificial skin sensor consists of a nxn matrix using CNFET, and the sensor outputs are connected to a current monitoring circuit proposed as the sensor interface circuit.
