Insole-type piezoelectric generator

Abstract

The invention provides an insole-type piezoelectric generator. The insole-type piezoelectric generator comprises an upper protective layer, a lower protective layer, at least one piezoelectric electricity generation unit and a power management module. The upper protective layer is placed above the lower protective layer, and the upper protective layer and the lower protective layer are both in an insole shape. The at least one piezoelectric electricity generation unit is placed between the upper protective layer and the lower protective layer. Each piezoelectric electricity generation unit comprises an upper tooth layer, a lower tooth layer and a piezoelectric thin film. The upper tooth layers are placed above the lower tooth layers. The lower surfaces of the upper tooth layers comprise upper racks and upper tooth grooves which are arranged in an alternating mode, the upper surfaces of the lower tooth layers comprise lower tooth grooves and lower racks which are arranged in an alternating mode, the upper racks are opposite to the lower tooth grooves, and the upper tooth grooves are opposite to the lower racks. The piezoelectric thin films are placed between the upper tooth layers and the lower tooth layers. The power management module is placed between the upper protective layer and the lower protective layer, and the power management module is connected with the piezoelectric thin films in all the piezoelectric electricity generation units. The insole-type piezoelectric generator is simple in structure, comfortable in foot feeling, and suitable for common shoes.

Description

technical field [0001] The invention relates to the field of new energy, in particular to an insole-type piezoelectric generator. Background technique [0002] In daily life, the human body consumes energy all the time and dissipates it in the environment. Taking advantage of this feature, people have designed various wearable devices for harvesting energy from the human body. Among them, the in-shoe generator that can collect human body motion energy is an important direction. At present, typical in-shoe generators include in-shoe piezoelectric generators stacked with piezoelectric ceramics, composite in-shoe generators and electrostatic generators made of piezoelectric ceramics and piezoelectric films. Although such in-shoe generators play the role of energy collection, they all have the disadvantages of poor universality, poor comfort, complex structure and insufficient durability, which is not conducive to the marketization and commercialization of in-shoe generators. ...
