AI Technical Summary
Existing flexible haptic feedback actuators suffer from problems such as high voltage requirements, weak output force, small frequency response bandwidth, weak vibration, and limited application scenarios, making it difficult to provide diverse haptic feedback and a realistic and natural interactive experience.
A multilayer composite stiffness elastomer structure is prepared by using a stacked first electrode layer, a dielectric film, and a second electrode layer. The first electrode layer consists of two or more layers of elastomers with composite stiffness, with at least two layers having different stiffnesses. By combining silicone materials such as PDMS, Ecoflex, and SEBS, and adjusting the stiffness combination of the layers, a multilayer composite stiffness elastomer structure can be prepared.
It achieves high output force feedback under low voltage, has a large frequency response bandwidth, and programmable haptic feedback, enabling it to provide diverse haptic experiences in various application scenarios and is suitable for under-display integrated applications.
