Force–Displacement Characterization of PNIPAM Microactuators

Advanced Robotics Research, EarlyView.
A method to experimentally establish a force–displacement diagram of poly(N‐isopropyl acrylamide) (PNIPAM) microactuators, printed by 2PP, is presented herein. PNIPAM is a hydrogel whose volume and stiffness change with temperature due to the absorption or release of water.

In situ preparation of PNIPAM biphasic hydrogels

European Polymer Journal, 2023
N-isopropylacrylamide (NIPAM) monomer undergoes phase separation in water at very high concentrations, which offers striking opportunities to engineer biphasic hydrogel systems. However, this is a metastable state and NIPAM evolves to crystallize. Besides, the concentration of NIPAM in the lower phase is very small.
