Researchers Develop an Ultra-Compact Injectable Temperature-Sensing Chip, Powered by Ultrasonics
Small enough to be injected through a small needle, this wireless temperature sensor shows promise for future medical procedures.

Researchers from Columbia University and Delft University of Technology have created ultra-compact "implantable motes" that can report on localized temperature within the human body and which are powered entirely from ultrasonic signals â all on a single, tiny chip.
"We wanted to see how far we could push the limits on how small a functioning chip we could make," Professor Ken Shepard explains of the study he led." This is a new idea of 'chip as system' â 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."
