Problems solved by technology

In these two studies, cellophane and PDMS were used as the connection layer between multiple pieces of IPMC, which can be considered as the prototype of the array flexible driver. However, the relevant research teams stayed on the improvement of the bionic form of the driver, and did not carry out any research on the driver components. Design and explore further
It can be seen that the research on IPMC-based flexible actuators has achieved certain results, but the research on complex curved surface actuators is still in the exploratory stage; some of the existing IPMC-based flexible actuators only use the single-degree-of-freedom bending of IPMC Although some are studying multi-degree-of-freedom bending deformation, they have not used the sensing function, and the distribution design and research of array flexible actuators with both sensing and actuation functions are almost blank

Abstract

The invention discloses an IPMC-based array type flexible curved surface self-sensing driver and a preparation method thereof, which is characterized in that: both the upper and lower surfaces of the polyelectrolyte flexible base layer are provided with a plurality of sheet electrodes in an array; The sheet electrodes on the upper and lower surfaces are symmetrical one by one, and the two symmetrical sheet electrodes and a part of the polyelectrolyte flexible matrix layer sandwiched between the two sheet electrodes form sensing functional elements or actuating functional elements; There are circuits extending outward from the edges of the electrodes; the preparation method is: forming sheet electrodes and circuits on the polyelectrolyte flexible substrate layer by means of a mask, or by laser cutting after overall plating. The self-sensing driver of the invention has a simple process, and utilizes the characteristics of the IPMC having both a sensing function and an actuating function, so that precise control of the deformation position of the curved surface of the flexible curved surface driver can be realized.

Description

technical field [0001] The invention relates to an array type flexible curved surface self-sensing driver based on ionic polymer-metal composites (Ionic Polymer-Metal Composites, IPMC) and a preparation method thereof, belonging to the field of preparation and application of ionic electro-actuated polymers. Background technique [0002] Flexible actuators are the key components of flexible mechatronics. In the emerging science and technology of this century, flexible mechatronics is one of the core technologies in the important development fields of human future industries such as bionic robots, artificial intelligence, and wearable medical care. Different from traditional rigid mechatronics, flexible mechatronics abandons complex mechanical transmission devices, and usually realizes complex terminal motions based on functional polymers or polymer-based composite materials. [0003] As the host material for flexible actuators, ion-type electroactuated polymers not only have ...
