2024

Soft haptic devices could enable unique applications in AR/VR, healthcare, and human-machine interface systems. Here, a versatile reconfigurable haptic system is proposed for different application scenarios at diverse anatomical locations and body shapes. Lego toys are the inspiration of the module concept where individual haptic modules can be cut, reconfigured, and reconnected as a new system in the ambient environment repeatedly.

Each module consists of the basic building block of flexible selfhealable ion-conducting and insulating layers....

2024

We present a surface-tension driven electrochemical liquid metal (LM) actuator without the gas-producing sidereaction and capable of fabrication/operation in ambient air for practical applications. A hybrid supercapacitor is introduced to inhibit the common counter electrode side reactions, and the use of quasi-solid-state ionic hydrogel instead of liquid electrolyte further enables non-volatile operations. A 2×4 LM droplet array is demonstrated to actuate by a low driving voltage of 3.5 V for a maximum force of ~8.5 mN and a displacement of 0.56 mm in only 1.75 s. With the favorable...
