Nonlinear Conductive Graphene Composites for Pressure Sensing with a Linear Response and Voltage‐Driven Thermal Correction

Abstract Thermal fluctuations pose a significant challenge to the signal stability of nanomaterial‐based piezoresistive pressure sensors, limiting their effectiveness in applications such as electronic skin and robotics. Conventional temperature compensation strategies often rely on additional thermal sensors or complex calibration algorithms. Here, a flexible pressure sensor is reported featuring a nonlinear conductive graphene composite layer within a bilayer architecture, enabling bias voltage‐controlled sensitivity without structural redesign. The sensor achieves ultra‐high sensitivity (742.3 kPa −1 ), a broad linear sensing range of up to 800 kPa ( R 2 = 0.99913), and excellent long‐term durability over 10 000 cycles. Crucially, the unique nonlinear characteristics enable the bias voltage to function as an internal remote control for correcting temperature drifts between 25 and 60 °C, as demonstrated by precise manipulation in robotic grippers under varying temperature conditions. This work offers a universal strategy for building environmentally adaptive sensors, advancing the development of robust and high‐precision wearable electronics.
