Embodiment Construction

[0043] The present invention will be further described below in conjunction with accompanying drawing.

[0044] Such as figure 1 The graphene eye-moving piece shown, the graphene eye-moving piece includes a flexible substrate 1d, a graphene nano-wall 1a arranged on the flexible substrate 1d, and a graphene nano-wall 1a arranged on the graphene nano-wall 1a for input / The first electrode 1b and the second electrode 1c that output electrical signals. The flexible substrate 1d is made of polydimethylsiloxane.

[0045] Graphene is a planar hexagonal lattice material formed by sp2 hybridized carbon atoms connected by covalent bonds. It can be warped into zero-dimensional fullerene, rolled into one-dimensional carbon nanotubes or other planar shapes, and has Tunable band gap, room temperature Hall effect, extremely high mechanical strength elasticity and thermal conductivity, extremely fast electron transport, good flexibility and biocompatibility, etc.

Description

technical field [0001] The invention belongs to medical equipment, and in particular relates to a graphene eye movement sheet, an eye movement psychological regulator and an eye movement testing method. Background technique [0002] Eyes are the most important information input system in our information processing process. By studying these movements of the eyes, researchers can explore the laws of human cognitive activities. In order to accurately record people's eye movement process, psychologists and other relevant experts have been working hard to develop eye movement recording technology. Early eye movement studies mainly used observation methods and mechanical recording methods. The error of the observation method is very high, and the mechanical recording method includes various forms such as the head fulcrum lever method, the pneumatic method, and the corneal adsorption ring method. The observation method is simple and easy to implement, but the result is imprecis...
