Direct comparison of PNIPAm, PVA, and KBT composites. a Dielectric constant (ε′) and loss tangent (tan δ) of hydrogels in RF frequency range at 27 °C. Characteristics of polarization contributions to the dielectric measurements begin at ~ 100 kHz for KBT800, ~ 20 kHz for PNIPAm, and ~ 10 kHz for PVA. b Conductance of KBT, PVA, and Bulk PNIPAm at 27 °C
