3D printed hydrogel "bio-bots" powered by muscle cells

Combining biological components, such as cells and tissues, with soft robotics can enable the fabrication of biological machines with the ability to sense, process signals, and produce force. Engineers at the University of Illinois are working on developing a Bio-Robot which can be produced easily by using 3D printing technology. They developed similar bio-bots few years back, but that time they used heart cells. Now they find a way to use muscle cells to gain more control. The frequency of the electric field determines the speed of this bio-bot.
