MIT engineers create paper thin robot powered by living muscle cells

Engineers at the Massachusetts Institute of Technology have built a paper thin swimming robot powered by living muscle cells, ScienceDaily reported. The tiny biological machine responds to flashes of light, which allow it to swim and steer through water without traditional mechanical motors. [1]

According to ScienceDaily, the design uses a single engineered layer of living muscle cells to generate propel force. Researchers demonstrated that this single cell layer creates sufficient movement to drive the miniature device through aquatic environments. [1]

The development builds on broader advances in light controlled biological technology. As HEROIC BREAKING NEWS reported earlier, researchers Karl Deisseroth, Peter Hegemann, and Georg Nagel received the 2026 Nobel Prize in Physiology or Medicine for optogenetics, a technique using light to control cellular activity.

ScienceDaily reported that this development could enable the creation of self healing biological robots. These small devices may eventually explore and monitor fragile environments that traditional rigid machines cannot safely navigate. [1]
