Tiny, wireless, injectable chips use ultrasound to monitor body processes

Soon, ultrasound may be used for more than monitoring unborn babies. Said to be “the smallest single-chip system that is a complete functioning electronic circuit”, the chip is powered by and transmits information using ultrasonic waves, as its size means it can’t carry a battery of its own, nor utilise radio frequencies. Although it currently can only measure temperature, the researchers plan to expand its use to track other vitals, including monitoring glucose and blood pressure. Read full article here
