Scientists have invented a dissolvable brain implant the size of a grain of rice

A surgical implant no bigger than a grain of rice which measures a patient’s temperature and blood pressure for several days before dissolving harmlessly in body fluids has been invented by scientists. The biodegradable device could be implanted into the brain or other vital organs to monitor a patient’s medical recovery without the need for cumbersome wires or operations to remove the implant once its job is done, the researchers said.
