Time-dependent response of PNIPAm, PVA, and KBT to applied RF. Images of PNIPAm, KBT, and PVA hydrogels undergoing exposure to RF at 544.4 kHz in a parallel plate antenna setup. Bulk PNIPAm (top) does not show any discernible volumetric change while KBT (2nd row) and PVA (3rd row) show RF-induced volumetric changes. PVA undergoes the most extensive volumetric phase change within 10 min of application, while KBT at 20 min of application. Bulk PNIPAm after undergoing its phase change attained using conductive heating (bottom)
