Multifunctional friction-generating floor leather and sensor

Abstract

The invention discloses multifunctional friction-generating floor leather and a sensor. The multifunctional friction-generating floor leather comprises a floor leather body and a conductive layer element. The floor leather body and the conductive layer element are combined into a whole and located in the same plane, an electrode led out , and thus the single-electrode integrated friction-generating floor leather is formed. The floor leather body serves as a first friction layer, and surfaces of insulating materials and non-insulators in daily life serve as a second friction layer; according to theories of electrification by friction and electrostatic induction, the two friction layers make contact with or are separated from each other so as to generate potential differences between an electrode layer element and the ground; and the conductive layer element can output electrical signals to external circuits, and serve as an independent sensor. The multifunctional friction-generating floor leather is based on improvement of common floor leather in the market, and is simple in structure, low in material consumption, low in cost, easy to prepare, and capable of outputting electrical signals, and the application range and service life of the floor leather are not limited.

Description

technical field [0001] The invention belongs to the technical field of friction generators, and in particular relates to a multifunctional friction generator floor leather and a sensor. Background technique [0002] Mechanical energy is ubiquitous in current life, but it is widely ignored by people. The invention utilizes the basic idea of ​​converting mechanical energy into electric energy by using the principles of friction electrification and static induction, and provides a multifunctional friction power generation floor leather. The friction power generation floor leather is laid indoors, and the mechanical energy generated by people walking, stepping on, touching, etc. is converted into electrical energy to provide electrical signals for external circuits, forming a green and environmentally friendly power generation method. The multifunctional friction power generation floor has multiple functions. When the power generation multifunctional floor leather is triggered ...
