Magnetic e-skins enabled somatic and touch-less interactive devices
Jin, G.; Xu, W.; Gilbert Santiago, C. B.; Jürgen, F.; Denys, M.;
Humans skin provide perceptions of the temperature of objects, strain and pressure on skin, friction for holding objects, which help humans interact with unstructured surroundings very precisely. Electronic skins [1,2] allow for the realization of similar sensing functions and also having the possibility of integrating other sensing functions beyond humans. Very recently we demonstrated magnetosensitive e-skins, which is an important step towards the realization of artificial magnetoception for humans [3,4].
Here, we present a magnetic e-skin that not only is sensitive to mechanical forces and deformation, but also has the ability to detect the position and movement of magnetic objects in a touch-less manner. The magnetic skin is a stack of a wrinkled magnetic sensor layer and a pyramid-structured magnetic foil. The GMR sensor enables the sensing of the movement of the remote magnetic objects (touch-less interaction). Furthermore, the distance change between the sensor and the magnetic foil make the magnetic skin sensitive to pressure, stretch and flexion (somatic interaction). This magnetic e-skin will hold great promise for the realization of humanoid robots, biomedical prostheses, and surgical electronic gloves.
