Engineers at Columbia University in the United States have developed a chip that is only visible through a microscope. Its size is comparable to that of a house dust mite. The aim of the device will be to monitor biological processes in the human body using ultrasound.
According to the researchers, it is the smallest chip in the world with a total volume of 0.1 mm3. It could be used to monitor physiological conditions such as blood pressure, temperature, glucose, respiration for both therapeutic and diagnostic procedures.

To achieve this size, engineers led by Ken Sheperd, professor of electrical engineering at the Lau family, used ultrasound to wirelessly power and communicate with the device. “We wanted to see how far we can push the limits of the functionality of a functional chip,” said the teacher according to a statement.
According to Sheperd, this technology should revolutionize the development of implantable, miniaturized, and wireless medical devices that allow various things to be recognized and approved for human use.
