Rory Murphy, a neurosurgeon at the Washington University School of Medicine is part of a team developing a sensor that can measure pressure, temperature, and more before being safely absorbed into the body. Via The Atlantic
As a neurosurgeon at the Washington University School of Medicine, Murphy “deals with brain trauma all the time.” Between bullets, blunt forces, and blood clots, traumatic brain injuries kill around 50,000 people in the United States every year. These kinds of injuries often cause the brain to swell, which constricts the flow of blood and oxygen, and can lead to permanent damage. So surgeons like Murphy need reliable ways of monitoring the pressure inside their patients’ skulls. Sensors exist, but they are large, clunky, and must be removed once the patient has recovered.
Together with a team of engineers, Murphy is developing a better option: a dissolvable pressure sensor. Thinner than the tip of a needle, it can be left in a patient’s brain to take accurate readings for several days, before completely disappearing. You don’t need to remove them because there’s nothing to remove. They just get absorbed into the body.
