That hasn't stopped it from filing yet another one though, as the latest application reveals a fingerprint sensor apparently embedded into the iPhone itself.
They are now working on adding improvements, like live data web-hooks, which make it possible to write a web app that talks to a sensor without first learning about embedded programming, electronics or networking.
The material uses what the researchers are calling 'shape-memory' polymers and have a fiber optic network embedded within them which acts as the damage sensor as well as the heat delivery system.
