A new Concept for Self-Assembling Micromachines

Wheel mounting in seconds: as soon as a non-uniform electric field is switched on, the chassis of a microvehicle pulls its own wheels into wheel pockets. After just over a second, all the wheels are in place.

In the future, designers of micromachines can utilize a new effect. A team led by researchers from the Max Planck Institute for Intelligent Systems in Stuttgart have presented a concept that enables the components of microvehicles, microrotors and micropumps to assemble themselves in an electric field. The new
