Novel radio frequency microwave energy acquisition device based on electron spin property

Abstract

The invention provides a novel radio frequency microwave energy acquisition device based on an electron spin property, which comprises at least one radio frequency microwave energy conversion part. The radio frequency microwave energy conversion part comprises a first magnetic layer, a non-magnetic space layer and an energy conversion layer, wherein the first magnetic layer is connected with a radio frequency microwave signal receiving part; and the energy conversion layer accumulates positive and negative charges at the upper and lower ends of the radio frequency microwave energy conversion part to convert the radio frequency wave energy into DC signals. Compared with the prior art, the novel radio frequency microwave energy acquisition device based on the electron spin property has the advantages that the structure is simple, the size is small, the working frequency is wide and the like.

Description

technical field [0001] The invention relates to a radio frequency microwave energy acquisition technology, in particular to a novel radio frequency microwave energy acquisition device based on electron spin properties. Background technique [0002] With the rapid development of large-scale integrated circuit manufacturing technology and ultra-fine processing technology, micro wireless sensors and micro-electromechanical systems (MEMS) have been or will be widely used in industry, agriculture, military, aerospace, medicine, environmental monitoring and home services, etc. Many fields. Current wireless sensor sites and MEMS systems are powered by batteries or cables. However, in some applications, such as installing scattered wireless sensors in the field, it is unrealistic to use batteries or cables for power supply. Even with battery power, regular mass replacement is quite difficult. Therefore, energy supply is an important problem to be solved in current wireless sensor...
