Glossary of Terms
Haptic TechnologyA technology that provides the sense of touch to the user through forces, vibrations or motions. For medical procedures, haptic interfaces can improve minimally-invasive surgery by relaying the sense of pressure and touch through the instruments used by the surgeon. Haptic technology has been introduced into the design of prosthetics to provide sensory feedback to the user.
HydrogelA biomaterial made up of a network of polymer chains that are highly absorbent and as flexible as natural tissue. Hydrogels have a number of uses including as scaffolds for tissue engineering, as sustained release drug delivery systems, and as biosensors that are sensitive to specific molecules such as glucose.
