What Makes the Electronic Insects Move Their Wings?
Robotic moving insects are made possible because of a new “wire muscle” technology that makes their wings move silently with very few moving parts. This “wire muscle” technology has also been used in other forms of robotics, prosthetics and on the recent NASA Mars Rover. This single strand of wire is made of a special nickel-titanium alloy that contracts, like a muscle, when heated by an electric current and relaxes again when the current ceases.
