Chinese research team creates tiny, wireless brain sensor

The sesame seed-sized, biodegradable brain sensor. CHINA DAILY Chinese researchers have developed a sesame seed-sized, biodegradable and wireless brain sensor that could potentially transform the way brain conditions are monitored in patients with head injuries or tumors. To address these problems, researchers at Huazhong University of Science and Technology in Wuhan, Hubei province, along with those from Tong Ji Hospital in the city and Nanyang Technological University in Singapore, created a cubeshaped wireless sensor measuring 2 millimeters on each side. Researchers tested the sensor in rats and pigs and found that it can perform as well as or even better than conventional wired sensors when measuring intracranial pressure and temperature. He said the team's research is nearing clinical application, but more efforts are needed to deepen collaboration with doctors, test the sensor's effects in human bodies after rigorous ethical and technological review, and explore ways to use the technology on an industrial scale.
