A window to the brain: an interview with Professor Guillermo Aguilar, UC Riverside's Bourns College of Engineering (BCOE)

It is literally a transparent window made of yttria-stabilized zirconia (YSZ), which we envision to become a suitable cranial implant that allows physicians for optical access to the tissue brain. It would serve the same mechanical function of current cranial implants made of other materials, such as titanium, except that it would enable optical access too, which could be very beneficial for post-operatory diagnostic or therapeutic procedures.
