The invention provides an
electronic skin of a friction
electrostatic induction type, and the
electronic skin comprises a friction layer, an upper
electrode, an insulating layer, a lower
electrode and a flexible substrate, wherein the friction layer, the upper
electrode, the insulating layer, the lower electrode and the flexible substrate are sequentially arranged in a fixed manner from the top to the bottom, and the upper and lower electrodes are insulated from each other. Each intersection point of the upper and lower electrodes represents one detection position. When
human skin touches any detection position, the corresponding electrodes of the upper and lower electrodes respectively output a
signal, so the touch position can be obtained. The
electronic skin employs the friction
electrostatic induction effect, and generates an
electric signal through the contact and separation of a
human body with the friction layer, so as to sense the touch condition of an external object. The electronic
skin has a self-drive function, is good in stability, is high in sensitivity, and is quick in response. Meanwhile, the electronic
skin employs a flexible
polymer thin
film material with the
biocompatibility, and is wide in application range.
