Short summary
Soft pressure sensors fabricated by means of carbon-based material and polymers have the potential to sense pressure starting from 2 g to 18 kg. Such pressure sensors also exhibit high sensitivity, high durability, easy integration and long-term stability. These sensors can be integrated into robotic parts like fingers and feet to monitor the grasping force and the gait of the robot respectively.
