Abstract

The invention provides a sliding electrostatic energy trapping device for human heart beating. The energy trapping device is applied to the collecting of the energy of human heart beating. The energytrapping device comprises two energy trapping parts and an attachment part. The energy trapping part comprises an inner substrate, an outer substrate and a dielectric material layer arranged on the surface of the substrate. The dielectric material layers on the inner and outer substrate surfaces are in contact with each other and have opposite polarities. The dynamic signals of heart beating are transmitted to the energy trapping units through the attachment unit, so that friction occurs between the dielectric material layers on the surface of the inner and outer substrates, positive and negative charges are generated respectively, and potential energy is formed and input to the implantable electronic equipment. The invention has the advantages of long service life, easy integration with other processing processes and high energy conversion rate.

Description

technical field [0001] The invention relates to a sliding friction power generation energy harvesting device, in particular to a sliding friction power generation energy harvesting device for human heart beating. Background technique [0002] Today, human body-embedded electronic devices are widely used in the medical field, and their energy consumption has attracted much attention. Generally, the battery energy of human body-integrated electronic devices will be exhausted in 5 to 7 years, and it is necessary to replace the battery Surgery is cumbersome and expensive, and harvesting the energy of heart beats may be an ideal solution to this problem. At present, the research ideas on heart energy harvesting are mainly divided into collecting the energy of heart beat and collecting the energy of cardiac chamber pressure difference. The energy sensors used are mainly divided into electromagnetic, electrostatic, and piezoelectric, but they are limited to materials and process le...
