Injectable wireless chip to monitor body processes invented at Columbia University Satsuki Then - May 12, 2021, 5:02am CDT Engineers at Columbia University have created a tiny, wireless, and injectable chip used to monitor body processes powered by ultrasound. The device is said to be the smallest single-chip system that is a complete functioning electronic circuit. The implantable chip is visible only under a microscope and leads the way towards developing chips that can be injected into the body using a hypodermic needle. Researchers are interested in wireless, miniaturized implantable medical devices for in vivo and in situ monitoring of all manner of medical conditions, including temperature, blood pressure, glucose, and respiration for diagnostic and therapeutic procedures. Current implanted electronics are a challenge and can’t be produced in high volume because they require multiple chips, packaging, wires, external transducers, and batteries for energy storage. Columbia researchers have designed a system they say is the world’s smallest single-chip system with a total volume of less than 0.1 mm3.
