Spontaneous oscillations on the order of several hertz are the drivers of many crucial processes in nature. From bacterial swimming to mammal gaits, converting static energy inputs into slowly oscillating power is key to the autonomy of organisms across scales. However, the fabrication of slow micrometre-scale oscillators remains a major roadblock towards fully-autonomous microrobots. Here, we study a low-frequency oscillator that emerges from a collective of active microparticles at the air… 

Solitary states in complex networks: impact of topology

The dynamical behavior of networked systems is expected to reflect the properties of their coupling structure. Yet, symmetry-broken solutions often occur in symmetrically coupled networks. An example



Coordinating an Ensemble of Chemical Micromotors via Spontaneous Synchronization.

This quantitative, systematic study of synchronizing micromotors could facilitate the design of biomimetic nanorobots that spontaneously communicate and organize at micro- and nanoscales.

Self-Propelling Nanomotors in the Presence of Strong Brownian Forces

A scheme to realize artificial Janus nanoparticles (JNPs) with an overall size that is comparable to that of some enzymes ∼30 nm, which can catalyze the decomposition of hydrogen peroxide to water and oxygen and thus actively move by self-electrophoresis.

Chemically-powered swimming and diffusion in the microscopic world

This Perspective describes recent advances of chemically-powered swimming or diffusion of objects on the molecular scale, nanoscale and microscale and evaluates the reliability of common techniques to measure diffusion coefficients and finish.

Soft phototactic swimmer based on self-sustained hydrogel oscillator

A self-sustained soft oscillator that exhibits perpetual and untethered locomotion as a phototactic soft swimming robot, remotely fueled and steered by constant visible light is reported, and high-speed and controllablePhototactic locomotion is demonstrated.

Photothermocapillary Oscillators.

This work presents a new class of tunable light-driven oscillators based on mm-scale objects adsorbed at fluid interfaces and is the first example where Marangoni and capillary forces combine to incite sustained motion.

Low rattling: A predictive principle for self-organization in active collectives

A unifying framework that models the behavior of complex systems as largely random while capturing their configuration-dependent response to external forcing is offered, which allows derivation of a Boltzmann-like principle for understanding and manipulating driven self-organization.

Catalytically powered dynamic assembly of rod-shaped nanomotors and passive tracer particles

Short-range attractive interactions of catalytic nanorod motors were shown to arise from electrical forces, which drive the transient formation of dimers and trimers, and are also responsible for the collection of passive tracer particles at the ends of the nanorods.

Chemically Controlled Spatiotemporal Oscillations of Colloidal Assemblies.

An autonomous oscillatory micromotor system in which active colloidal particles form clusters, the size of which changes periodically, is reported, governed by an electrolytic self-diffusiophoretic mechanism which involves alternating electric fields generated by the competing reduction and oxidation of silver.

Microrobot collectives with reconfigurable morphologies, behaviors, and functions

This work presents a versatile microrobotic collective system capable of on-demand reconfiguration to adapt to and utilize their environments to perform various functions at the air–water interface.
