Researchers at the University at Buffalo (UB) have developed an electronic textile (e-textile) that enables robots to sense pressure and detect subtle movements, mimicking the human sense of touch. This advancement aims to improve the safety and precision of human-robot collaborations in various settings, including manufacturing and healthcare.
The e-textile functions similarly to human skin, offering flexibility and high sensitivity. It can detect not only pressure but also subtle slippage and movement of objects. This capability is achieved through the tribovoltaic effect, where friction between materials generates direct-current electricity, allowing for rapid response times comparable to human touch receptors.
Integrating this sensor into robotic systems enables them to adjust grip force dynamically, enhancing their ability to handle objects delicately and safely. This technology holds promise for applications such as robotic surgery tools and prosthetic limbs, where precise and responsive touch is crucial.
Future research aims to incorporate artificial intelligence to further enhance the robot's dexterity and adaptability, paving the way for more seamless human-robot interactions.
