Embodiment 1

[0045] Such as Figure 1-4 As shown, a bionic tactile sensor based on a triboelectric nanogenerator includes a carbon fiber touch rod 1, an upper limit plate 2, four support rods 4, four power generation units 5, a base 6, an octahedron touch block 8, Memory metal spring 9 and adjustable bolt 10. The touch block 8 is designed as an octahedron so as to achieve the best touch effect with the power generation unit 5 . The touch rod 1 is made of a tough carbon fiber rod so as to sensitively recognize the characteristics of external contact objects. A series of designs such as the tough carbon fiber rod, the silicone package of the upper limit plate, and the memory metal spring 9 can help the touch rod 1 return to the center after touching an external object.

[0046] The upper limit plate 2 and the base 6 are connected by four support rods 4, and the four support rods 4 are evenly spaced in the circumferential direction. The upper limit plate 2 is provided with an upper limit po...

Abstract

The invention provides a bionic tactile sensor based on a friction nanometer generator. The sensor comprises a supporting device which is composed of four supporting rods, an upper limiting disc, and a pedestal; a touch sensing device is connected with the supporting device and is composed of a touch rod making contact with an external object, a touch block connected with the touch rod, a front power generation unit, a rear power generation unit, a left power generation unit and a right power generation unit, the touch block is connected with an adjustable bolt through a memory metal spring, and the adjustable bolt is connected with a threaded hole in the pedestal; the touch rod transmits an external force to the power generation unit through the touch block under the action of an external object, the power generation unit generates inductive charges, and a signal for sensing the external object is output by a wire connected with the power generation unit; and after the external force disappears, the touch rod restores to an original position. The sensor is reasonable and firm in structural design, can resist interference caused by self movement, and can sensitively sense the characteristics of the external object; and a sensing system is formed by a bionic tactile sensor array so that a sensing capability is improved, and the bionic tactile sensor array is of great significance to exploration of a complex environment.

Description

technical field [0001] The invention relates to the technical field of triboelectric nanometer power generation, in particular to a bionic tactile sensor based on a triboelectric nanometer generator. Background technique [0002] As a direct perception method, tactile sensing has shown great advantages in object recognition. In noisy, dark, and cramped environments, tiny, accurate perception is especially important for us to explore unknown territories. At present, the commonly used touch sensing devices are mainly pressure sensing, but their ability to perceive complex and harsh environments will be greatly limited, and how to accurately sense external objects has become the main purpose of our research. Contents of the invention [0003] According to the above-mentioned technical problem that the currently commonly used touch sensing devices are mainly pressure sensing, but their perception ability will be greatly limited for complex and harsh environments, a bionic dev...
