Electret self-power generating device and electret self-power generating smart shoes

Abstract

The invention provides an electret self-power generating device and smart shoes. The electret self-power generating device comprises an elastic base carrier internally provided with a cavity, a rigidcarrier arranged opposite to the elastic base carrier, an electret thin film fixedly arranged between the elastic base carrier and the rigid carrier, a lower electrode arranged on the elastic base carrier and opposite to one surface of the electret thin film, and an upper electrode arranged on the rigid carrier and opposite to another surface of the electret thin film. Under the action of an external force, the elastic base carrier deforms and squeezes the cavity to enable the cavity to be correspondingly deformed, so that the electric field between the upper electrode and the electret thin film and the electric field between the lower electrode and the electret thin film change, thus converting mechanical energy into power energy. The self-power generating device and the smart shoes are capable of fully using the mechanical energy generated by the human body during the process of walking or running, and converting the mechanical energy into power energy so as to solve the problem of power supplying. The conversion efficiency from a voltage, an electric current and kinetic energy into the power energy is greatly improved, thereby facilitating the use of a portable smart device.

Description

technical field [0001] The invention relates to the field of wearable intelligent design, in particular to an electret self-generating device and electret self-generating smart shoes. Background technique [0002] With the continuous progress of society, wearable mobile Internet devices are gradually becoming a reality, and smart shoes have emerged as the times require. At present, most of the common smart power generation shoes use magnetoelectric power generation, or need to install a small lithium battery in the sole circuit, which is not only complicated in structure and high in cost, but also the battery cannot be replaced. In addition, the piezoelectric material of the sole is also a commonly used method of power generation, but its power generation is very small and difficult to be utilized. The mechanical energy generated during walking is converted into electrical energy by friction power generation, which is collected and stored, and the mechanical energy generate...

AI Technical Summary

Problems solved by technology

At present, most of the common smart power generation shoes use magnetoelectric power generation, or need to install a small lithium battery in the sole circuit, not only the structure is complex, the cost is high, and the battery cannot be replaced

In addition, the piezoelectric material of the sole is also a commonly used power generation method, but its power generation is very small and difficult to be utilized

The mechanical energy generated when walking is converted into electrical energy by friction power generation, which is collected and stored, and the mechanical energy generated when walking can also be used reasonably. However, long-term use in this way will cause wear and tear of the power generation material, thereby reducing its effectiveness.
