NettetA soft dielectric membrane is prone to snap-through instability. We present theory and experiment to show that the instability can be harnessed to achieve giant voltage-triggered deformation. Nettet7. apr. 2024 · Liquid metal smart materials also play a vital role in this strategy. Li et al. implemented a soft logic system using the response of a liquid metal to an electric field. The team systematically demonstrated the concept of a soft logic unit based on liquid metal and designed two types of basic logic units (Figure 11a(i–ii)).
