World’s Smallest Implantable Chip Can Monitor Medical Conditions

The world’s smallest implantable chip that can monitor people’s medical conditions has been created.

Apparently the chip will be able to do an array of things, in addition to monitoring people’s medical conditions.

According to the university, it will be able to support and enhance physiological functions and treat diseases which will overall improve the patient’s quality of life.

Some of the physical conditions it’s hoped to be able to monitor include temperature, blood pressure, glucose, and respiration for both diagnostic and therapeutic procedures.

The total volume of the chip is less than 0.1 mm³  – around the same size as a dust mite – and therefore is only visible through a microscope. The researchers, whose study was published on May 7, used ultrasound power to communicate with the device wirelessly.

We wanted to see how far we could push the limits on how small a functioning chip we could make. This is a new idea of ‘chip as system’—this is a chip that alone, with nothing else, is a complete functioning electronic system.

This should be revolutionary for developing wireless, miniaturized implantable medical devices that can sense different things, be used in clinical applications, and eventually approved for human use.

The design of the chip is said to have been done by doctoral student Chen Shi before it was fabricated at the Taiwan Semiconductor Manufacturing Company with additional process modifications performed in the Columbia Nano Initiative cleanroom and the City University of New York Advanced Science Research Center (ASRC) Nanofabrication Facility, the release explained.

The current models only measure body temperature, but there are ‘many more possibilities’ the team are working on.
