Scientists have recently developed a new material combining porous platinum with a hydrogel matrix, capable of functioning as an actuator material. This new material has a wide range of potential applications due to its ability to quickly and precisely respond to external stimuli. It has the potential to be used in medical devices, robotics, and prosthetics. The material is composed of an interconnected network of porous platinum which is embedded within a hydrogel matrix, creating a material that can be triggered to deform, contract, and expand in response to changing environmental conditions. This material could be used to create a variety of devices capable of responding to the environment in a variety of ways. The most exciting potential use is in the field of prosthetics, as this material could be used to create prosthetic limbs that respond to the environment in a natural way.
