LONDON—A team of researchers from Washington University School of Medicine in St. Louis and the University of Illinois at Urbana-Champaign has created implantable electronic sensors that can measure intracranial pressure and temperature before being absorbed into the body.
This has the advantage of negating the need for surgery to remove the devices and the researchers believe the approach can be extended to monitoring activity throughout the body.
The devices are made mainly of polylactic-co-glycolic acid (PLGA) and silicone, and they can transmit accurate pressure and temperature readings, as well as other information. The researchers tested the sensors in baths of saline solution that caused them to dissolve after a few days. Next, they tested the devices in the brains of laboratory rats.
The researchers are now planning to test the circuits in human patients.
The research was published online Jan. 18 in the journal Nature.
