Millions of tiny little robots, like the ones unveiled by scientists at Cornell and the University of Pennsylvania, could be used to fight diseases inside the human body.
The researchers have built microscopic robots that consist of a simple circuit made from silicon photovoltaics – essentially the torso and brain – and four electrochemical actuators that function as legs.
When laser light is shined on the photovoltaics, the robots walk. [Read more…] about Millions of microscopic robots could be used to fight diseases inside the body
