Human-Machine Interaction Device


The City University of Hong Kong has developed an epidermal wireless human-machine interaction interface with haptic feedback. Wearing this lightweight, flexible e-skin system enables remote human-machine interaction and robot control, which can be used for nursing robots, surgical robots and new crown sampling robots.

Problem addressed

The current lack of haptic feedback in the field of human-robot interaction is addressed. This epidermal flexible system enables wireless robot control through the strain sensing of joint flexion and finger grasping, and also integrates a haptic feedback device to re-feed the robot's sense of touch to the operator.

  • Time-delay-free, wireless remote control of robots is realized with just a soft skin patch.
  • The touch sense felt by the robot are fed back to the human-machine interaction operator in real time.
  • The operator makes real-time adjustments based on haptic feedback, greatly improving the precision and realism of the controls.
Key impact
  • The entire flexible unit is thin, light,easy to wear, fully functional and low-cost.
  • As a nursing robot with haptic feedback, it allows for more realistic remote care.
  • As a surgical robot with haptic feedback, it improves the precision of surgery and reduces the dependence on a highly qualified surgeon.
  • As a COVID-19 sampling robot with haptic feedback, it improves the comfort of pharyngeal and nasal swabbing and avoids infections for the sampling staff.
