Abstract

Disclosed is an inflated dielectric elastomer hemispherical driver, relating to a driver. The hemispherical driver solves the problems of long response time, big noise, large size, large electricity consumption, complex mechanical structure, poor flexibility and poor simulation property on current drivers. A first pre-stretched elastomer membrane(4) is adhibited at the inner surface(2-1) of a first film(2)of the hemispherical driver and a second pre-stretched elastomer membrane(5) is adhibited at the inner surface(3-1) of a second film(3); the inner facade (4-1) of the upper end of the first pre-stretch elastomer membrane(4) is jointed with the inner facade (5-1) of the upper end of the second pre-stretched elastomer membrane(5); a hemispherical room(10) is developed between a first electrode(6) and a substrate(1). The hemispherical driver requires small driving power and has the advantages of low cost and light weight. The hemispherical driver is widely applicable in various fields, such as facial expression field, aerospace field, robot field, mechanical insect field, artificial muscle field, noise control field, tactile interface field, muscle restoration and growth field, and liquid and gas flow control field.

Description

technical field [0001] The invention relates to a driver. Background technique [0002] The driving methods of existing drives are mostly mechanical drive, hydraulic drive, and motor drive. These types of drives have the problems of long response time, high noise, large volume, large power consumption, complex mechanical structure, poor flexibility, and poor bionic performance. , which makes it difficult for existing drivers to be applied in aerospace, artificial muscles, facial expressions and other fields. Contents of the invention [0003] The purpose of the present invention is to solve the problems of long response time, large noise, large volume, large power consumption, complex mechanical structure, poor flexibility, and poor bionic performance of existing drivers, and to provide an inflatable dielectric Elastomer hemispherical drive. [0004] The technical scheme of the present invention is: the inflatable dielectric elastomer hemispherical actuator consists of a...
