Transducer powered by electrochemical reactions for operating fluid pumps in soft robots

The word robot may conjure images of hard, metallic bodies that are invulnerable to attacks. In modern day-to-day life, however, robots are hardly needed for defending against enemy attacks. Instead, they are required to perform more mundane tasks such as handling delicate objects and interacting with humans. Unfortunately, conventional robots perform poorly at such seemingly simple tasks. Moreover, they're heavy and often noisy.
