Programmable Microscale Actuation of Hydrogels With Tunable Response via Printing on Particles
Advanced Materials Technologies, EarlyView.We fabricate microscale hydrogels with precisely tunable phase transition temperatures (23–60 °C) by particle‐templated two‐photon polymerization using chemically tailored inks. Multi‐material printing enables stepwise thermal actuation through sequential volume changes at distinct VPTTs, while pH‐dependent hysteresis drives anisotropic actuation with ...
