Polymer film harvests energy from water vapour

MIT engineers have created a new polymer film that can generate electricity by drawing on a ubiquitous source: water vapour. The new material changes its shape after absorbing tiny amounts of evaporated water, allowing it to repeatedly curl up and down. Harnessing this continuous motion could drive robotic limbs or generate enough electricity to power […]
