Gears and cogwheels are elemental components of machines. They restrain degrees of freedom and channel power into a specified motion. Building and powering small‐scale cogwheels are key steps toward feasible micro and nanomachinery. Assembly, energy injection, and control are, however, a challenge at the microscale. In contrast with passive gears, whose function is to transmit torques from one to another, interlocking and untethered active gears have the potential to unveil dynamics and…

Surface-enabled propulsion and control of colloidal microwheels

It is reported that low-strength magnetic fields can reversibly assemble wheel-shaped devices in situ from individual colloidal building blocks and also drive, rotate and direct them along surfaces at velocities faster than most other microscale propulsion schemes.

Motor and Rotor in One: Light-active ZnO/Au Twinned Rods of Tunable Motion Modes.

Photochemically powered zinc oxide/gold (ZnO/Au) rods that exhibit multiple motion modes are designed and synthesized and envision that such attractive colloidal micromachines with controllable motions hold considerable promise for diverse practical applications.

Shape-encoded dynamic assembly of mobile micromachines

The dynamic self-assembly of mobile micromachines with desired configurations through pre-programmed physical interactions between structural and motor units is described, driven by dielectrophoretic interactions, encoded in the three-dimensional shape of the individual parts.

Dynamic and programmable self-assembly of micro-rafts at the air-water interface

This work built an out-of-equilibrium material system by designing competing interactions that are both dissipative and programmable and demonstrates programmable self-assembly and shows that a 4-fold rotational symmetry encoded in individual micro-rafts translates into 90° bending angles and square-based tiling in the assembled structures of micro-RAFTs.

Reconfigurable multi-component micromachines driven by optoelectronic tweezers

This work introduces light-driven micromotors and micromachines that rely on optoelectronic tweezers (OET), and demonstrates a range of new functionalities, including a touchless micro-feed-roller that allows the programming of precise three-dimensional particle trajectories.

Micromotors with asymmetric shape that efficiently convert light into work by thermocapillary effects

It is shown that microfabricated gears, sitting on a liquid–air interface, can efficiently convert absorbed light into rotational motion through a thermocapillary effect and is shown to be one of the strongest mechanisms for light actuation at the micron- and nanoscale.

Targeted assembly and synchronization of self-spinning microgears

The targeted formation of self-powered microgears from active particles and their autonomous synchronization into dynamical superstructures is shown, laying the groundwork for the autonomous construction of dynamical architectures and functional micro-machinery.

Bacterial ratchet motors

It is shown that asymmetric environments can produce a spontaneous and unidirectional rotation of nanofabricated objects immersed in an active bacterial bath and highlights the technological implications of active matter’s ability to overcome the restrictions imposed by the second law of thermodynamics on equilibrium passive fluids.

Swimming bacteria power microscopic gears

A class of systems in which aerobic bacteria Bacillus subtilis moving randomly in a fluid film power submillimeter gears and primitive systems of gears decorated with asymmetric teeth are described.

Biological nanomotors, driving forces of life.

This review compares myosin and kinesin motors to describe the principles underlying how motors convert chemical energy into mechanical movement, and describes how targeting these motors can be beneficial for human health.
