Tiny, Wireless, Injectable Chips Use Ultrasound to Monitor Body Processes

Technology has made it possible to monitor a patient and to map their biological signals to better understand and treat diseases in real time with tiny, wireless chips implanted into the patient’s body. Older technology has been far less effective because multiple, larger chips were required, and were not particularly reliable. According to Columbia Engineering researchers, they have created the smallest chip system, smaller than a dust mite. The accomplishment was largely due to the researchers’ interest in seeing just how small they could make the chips, and how they could push the limits of what a tiny chip can accomplish. 

On its own, the chip is an entire system that does not require any outside batteries or other devices to record data. Designed by Chen Shi, the chip has numerous functions, though it cannot send communications over an electromagnetic wave because it is too small. Instead it communicates through ultrasounds. Currently, the tiny device can only relay temperature data, but the team is looking into how to increase the types of data it can send.
