Performance of conventional strain sensors has always been limited by the nature of sensing materials used, and users have limited options of customizing the sensors for specific applications. Researchers in Singapore have developed flexible, stretchable, and electrically conductive nanomaterials called MXenes and fabricated strain sensors which are ultra-thin, battery-free and transmit data wirelessly. The sensors are 10 times more sensitive when measuring minute movements of industrial robotic arms, compared to existing technology. In precision manufacturing it helps improve the overall safety of robotic arms by providing automated feedback on precise movements with an error margin below one degree and eliminate the need for external cameras to monitor positioning. The wireless sensing system can collectively monitor the multisegmented exoskeleton actuations through a single database channel, largely reducing the data processing loading…read more.
