An intelligent soft material that curls under pressure or expands when stretched

Nanowerk  February 24, 2021 Existing perceptive soft actuators require complex integration and coupling between the discrete functional units to achieve autonomy and intelligently interact with humans and the environment. Researchers in China have developed actuators with embodied sensing, actuation, and control at the single-unit level by synergistically harnessing the mechanosensing and electrothermal properties of liquid metal (LM) to actuate the thermally responsive liquid crystal elastomer (LCE). They created multifunctional LM circuits on the LCE surface using a simple and facile methodology based on magnetic printing. The fluidic LM circuit can be utilized as a conformable resistive heater, and a sensory […]

Assembly in the air: Using sound to defy gravity

Phys.org  March 4, 2019 Researchers at the University of Chicago levitated particles using sound to study how clusters are formed. They found that at a minimum six particles are needed to change between different shapes. By changing the ultrasound frequency, they could make the particle clusters move about and rearrange. This opens new possibilities for manipulating objects to form complex structures, develop new products and tools in the fields of wearable technology and soft robotics…read more.
