Ultra-Thin, Battery-Free Strain Sensors for Industrial Robotic Arms

Fabricated using flexible, stretchable, and electrically conductive nanomaterials called MXenes, novel strain sensors were developed that are ultra-thin, battery-free, and can transmit data wirelessly. By controlling the surface textures of MXenes, researchers were able to control the sensing performance of strain sensors for various soft exoskeletons. The sensor design principles developed will significantly enhance the performance of electronic skins and soft robots.
