Abstract
The invention provides a low-voltage driven dielectric elastomer driver and a manufacturing method. In the stack structure of the dielectric elastomer driver, there are first electrode layers and second electrode layers on both sides of each layer of elastomer layer , its conduction mode is unique, and by reasonably controlling the mechanical properties such as the material, thickness, elastic modulus, relative permittivity and resilience of the elastomer layer, as well as reasonably controlling the thickness and conductivity of the first electrode layer and the second electrode layer The properties such as sex and flexibility can greatly reduce the driving voltage of the dielectric elastomer driver. Moreover, the dielectric elastomer driver is manufactured by using a raised frame structure, which can make it generate resonant motion under AC voltage, thereby increasing the overall driving effect of the driver.
Description
technical field [0001] The invention relates to the technical field of dielectric elastomer drivers, more specifically, to a dielectric elastomer driver capable of driving at low voltage and a manufacturing method thereof. Background technique [0002] Dielectric Elastomer (DE for short) is an elastic material with a high dielectric constant. It can change its shape after applying an external electric field, and it will return to its original shape after removing the external electric field. This process is accompanied by stress and strain. to convert electrical energy into mechanical energy. [0003] The dielectric elastomer driver (Dielectric Elastomer Actuator, referred to as DEA), which is composed of flexible electrodes coated on the upper and lower surfaces of the dielectric elastomer, is widely used in pocket or micro robots, micro aircraft, disk drives, and planar loudspeakers. , prosthetics, and electronic skin are known as a new generation of electroactive drivers...
