A passive wireless robotic gripper based on a mechanical metamaterial structure

Abstract

The invention discloses a passive wireless machine grabbing hand based on a mechanical metamaterial structure, which includes a graphene oxide layer of a mechanical metamaterial structure, a graphene layer of a mechanical metamaterial structure, an upper plate of a capacitor, a dielectric layer, and a lower capacitor. Plates, planar inductors, vias, substrates, anchor regions, the graphene layer of the mechanical metamaterial structure is located below the graphene oxide layer of the mechanical metamaterial structure, the double-layer mechanical metamaterial structure is located on the front of the substrate, and the center of the mechanical metamaterial structure The place is a pressure-sensitive capacitor composed of the upper plate of the capacitor, the dielectric layer and the lower plate of the capacitor. The lower plate of the capacitor is connected to the anchor area, and the anchor area is connected to the planar inductance on the back of the substrate through the through hole. The present invention is based on the LC resonant circuit The change of resonant frequency can realize the detection of the object on the grasping hand, and apply infrared light excitation to the grasping hand to realize the purpose of grasping the object. It has the advantages of high sensitivity, small measurement error, small size, low power consumption, and novel structure. .
