Mesodamp & Liquid Crystal Elastomer Actuators

Liquid Crystal Elastomers (LCE) is a radically new polymer system, akin to rubber, but with remarkable and unexpected properties that stem from its intricate molecular structure. This structure creates local anisotropy axis, which can rotate separately and independently of the rubber-elastic matrix. 

Mesodamp utilises the unique LCE property of soft elasticity, which combines the damping properties of a liquid with mechanical stability of a thermoset to produce levels of damping far above market leading technologies based in polyurethane or silicone.

Dynamic Actuation - the other fascinating effect, which promises ground-breaking applications and devices, is that LCEs reversibly contract and expand on heating and cooling, changing the length by a huge amount – up to 100-200%. This mechanical actuation allows us to design actuators, muscles, or an LCE engine working on a difference in temperature between two containers.

First invented in 1980s and 90s, LCEs are only beginning to penetrate into the industrial applications and design. CSP team members have been at the very beginning of this development, and we are now developing marketable LCE applications in vibration isolation, reversible grippers, microfluidics, and LCE engine converting waste heat into useful work.
