Caption: Driven by water gradients, a generator based on a PEE-PPy actuator and a PVDF piezoelectric element is repeatedly contracting and expanding on a 30°C moist substrate. This video relates to a paper that appeared in Jan, 11, 2013, issue of Science, published by AAAS. The paper, by M. Ma at Massachusetts Institute of Technology in Cambridge, MA, and colleagues was titled, “Bio-Inspired Polymer Composite Actuator and Generator Driven by Water Gradients.”
