HAIRS: Hydrogel-Actuated Integrated Responsive Systems Joanna Aizenberg, Harvard University Responsive behavior, which is intrinsic to natural systems, is becoming a key requirement for advanced artificial materials and devices, presenting a substantial scientific and engineering challenge. We designed dynamic actuation systems by integrating high{aspect-ratio nanocolumns or nanofins, either free-standing or substrate-attached, with a hydrogel layer. The […]
