DARPA developed a hydrogel sensor which monitors blood for infections at early stages, not a microchip for COVID-19 identification or location tracker

KEY TAKE AWAY

In collaboration with the private biotech company Profusa, researchers at DARPA developed a hydrogel sensor to detect infection. The hydrogel biosensor technology was developed with the aim of serving as an early identification system for infectious disease outbreaks, such as during pandemics and biological attacks. It is sensitive enough to identify signs of illness a few days before symptoms appear, but it cannot identify the cause of the infectious disease. The sensor can only measure markers of biochemical changes and immune response in the blood.
