Traditionally an injured brain requires several rounds of surgery, a mess of wires and exposed wounds in order to find out what’s happening. However, this could be about to change. A brain monitor, roughly the same size as a grain of rice, has been created by a lab at the University of Illinois at Urbana-Champaign. The mini device can monitor both the brain’s temperature and the pressure, before dissolving after use. The sensor currently used is implanted and connected to an external sensor, whilst it is efficient, it limits physical movement as a result of the wires coming out of the head which can also cause damage when removed.
