Artificial Muscles Created from Gold-Plated Onion Cells
American Institute of Physics (AIP)The onion, a humble root vegetable, is proving its strength outside the culinary world -- in an artificial muscle created from onion cells. Unlike previous artificial muscles, this one, created by researchers from National Taiwan University, can either expand or contract to bend in different directions depending on the driving voltage applied. The finding is published this week in the journal Applied Physics Letters.
