Microorganisms move in challenging environments by periodic changes in body shape. In contrast, current artificial microrobots cannot actively deform, exhibiting at best passive bending under external fields. Here, by taking advantage of the wireless, scalable and spatiotemporally selective capabilities that light allows, we show that soft microrobots consisting of photoactive liquid-crystal elastomers can be driven by structured monochromatic light to perform sophisticated biomimetic motions…

Bioinspired microrobots

This Review highlights soft, responsive and active materials for the development of (semi-)autonomous microrobots and shows that smart, stimuli-responsive materials can act as on-board sensors and actuators and that ‘active matter’ enables autonomous motion, navigation and collective behaviours.

Light Robots: Bridging the Gap between Microrobotics and Photomechanics in Soft Materials

Recent progress in soft microrobotics is highlighted based on light-responsive liquid-crystal elastomers and polymer networks, focusing on photomobile devices such as walkers, swimmers, and mechanical oscillators, which may ultimately lead to flyingmicrorobots.

Toward a living soft microrobot through optogenetic locomotion control of Caenorhabditis elegans

This work proposes an approach to engineering the genetic and nervous systems of a nematode worm and creating an untethered, highly controllable living soft microrobot (called “RoboWorm”), and finds that the phase difference between the worm body curvature and the muscular activation pattern generates the thrust force for crawling locomotion.

Microscopic artificial swimmers

It is shown that a linear chain of colloidal magnetic particles linked by DNA and attached to a red blood cell can act as a flexible artificial flagellum, which induces a beating pattern that propels the structure, and that the external fields can be adjusted to control the velocity and the direction of motion.

Printed artificial cilia from liquid-crystal network actuators modularly driven by light.

It is demonstrated that all-polymer microdevices can be fabricated using inkjet printing technology in combination with self-organizing liquid-crystal network actuators, exploiting the self-assembling properties of the liquid crystal to create large strain gradients, and light-driven actuation is chosen to allow simple and remote addressing.

Biomimetic cilia arrays generate simultaneous pumping and mixing regimes

It is demonstrated that the directed transport regime is Poiseuille–Couette flow, the first analytical model consistent with biological measurements of fluid flow in the embryonic node, and novel evidence for the existence of mixing in ciliated systems is provided.

Swimming by reciprocal motion at low Reynolds number

This work reports a symmetric ‘micro-scallop’, a single-hinge microswimmer that can propel in shear thickening and shear thinning fluids by reciprocal motion at low Re, and indicates that the net propulsion is caused by modulation of the fluid viscosity upon varying the shear rate.
