Abstract

We present two mechanical metamaterials on the micrometer scale that change their mechanical behavior under irradiation with a blue LED. First, we show an auxetic metamaterial with a Poisson’s ratio that can be tuned on a large positive to negative values. Second, we demonstrate a chiral metamaterial with a tunable twist per strain that also varies from positive to negative values. For both examples, numerical finite-element calculations agree well with the measurements. Both metamaterials have been fabricated by two-photon microprinting of liquid-crystal elastomers in the presence of a tunable quasi-static electric field to align the local liquid-crystal director.
