A Stretchable Capacitive Strain Sensor Having Adjustable Elastic Modulus Capability for Wide‐Range Force Detection

In the article, number 1901239 Yiwei Liu, Xincai Liu, and Run-Wei Li and co-worker report a stretchable capacitive force sensor capable of adjustable modulus and wide-range force detection (0.07 to 74 N) by mounting the sensor with springs of different elastic coefficients. A wireless measuring system is developed to display the detected force. The cover design is inspired by the traditional Chinese story of “Cao Chong Weighs the Elephant”.
