Description

Technical Field

[0001] The utility model relates to the technical field of electronic skin, in particular to a high-sensitivity electronic skin. Background Art

[0002] Using electronic devices to simulate human skin has become an emerging research field that has attracted great interest among researchers. It has broad application prospects in the fields of artificial intelligence and human-computer interaction. However, traditional rigid electronic devices are hard and brittle, unable to withstand large deformations, and unsuitable for integration on soft, non-planar surfaces. Therefore, new electronic products that break through traditional rigid electronic devices, namely flexible electronic devices, have become the focus of researchers. Although research on electronic skin has achieved many results, it also faces many problems, such as insufficient device sensitivity, multi-directional pressure measurement, narrow linear range, and complex manufacturing processes, which make mass production difficult.

[0007] Preferably, the inner layer of the electronic skin is arranged between two outer layers of the electronic skin, the inner layer of the electronic skin is a circuit layer, and the inner layer of the electronic skin is arranged in an insulating isolation layer between the first electrode layer and the second electrode layer. The first electrode layer and the second electrode layer are respectively provided with a plurality of positive contacts and a plurality of negative contacts arranged in parallel. The insulating isolation layer has a plurality of perforations, each perforation is used to expose a positive contact and a negative contact, and the positive contact is used to conduct the negative contact. When the outer surface of the electronic skin is squeezed and touched, the second electrode layer is electrically connected to the external control box unit via the electrical connector interface, which can improve the sensitivity of the electronic skin.

[0008] Furthermore, the outer layer of the electronic skin is made of sponge or silicone, which can be extremely close to the touch of skin tissue and has a good cushioning effect.

[0009] Furthermore, the thickness of the outer layer of the electronic skin is 0.1-1.0 cm, which can improve the sensitivity of the electronic skin in contacting external objects.

[0012] Furthermore, a positive contact and a negative contact are combined to form a pressure sensor. When the pressure value of the pressure sensor touching the human body outside is greater than 60 Newtons, the control box unit is triggered.

[0013] Furthermore, the high-sensitivity electronic skin also includes a hard plate layer. The inner layer of the electronic skin is located between the outer layer of the electronic skin and the hard plate layer.
