Abstract

Abstract: The ability of the skin to be pressure‐sensitive has prompted scientists to develop materials and equipment to simulate this function. Recently, flexible and stretchable artificial electronic skin has received increasing attention with its unique ability to detect subtle pressure changes. Pressure sensing is one of the key functions of electronic skin devices. Here, a stretchy and highly sensitive pressure sensor is developed that used a polydimethylsiloxane (PDMS) film with leather composite layer as flexible part. These features enable the sensor to accurately detect a variety of human activities, such as small finger movements and bending, pulse and so on. The sensor is found to have a good sensing signal for temperature. This feature provides great promise for sensors to detect temperature. Abstract : In this work, by replicating the complex structure of leather, a new type of stretchable and highly sensitive pressure sensor is developed. The sensor has high sensitivity, wide detection range, and short response time, which can be successfully applied to human body motion detection. Furthermore, the device enables the detection of temperature changes and provides intuitive color changes.
