The Boston Business Journal reports on the sensor, intended to be implanted during a biopsy. A key issue: How to get power to the thing. Magnets to the rescue.
While the team could make the sensor and its circuit board small enough to fit in the tip of a biopsy needle, researchers struggled to figure out a power source. Instead, scientists had the reading device create a voltage in the implant by issuing a magnetic field. The reader then interprets return signals, and look at changes over time to view changes in oxygen and acidity.
This is the same basic two-way technology behind most RFID readers these days. Magnetically derived voltage operates a chip and that sends back a readable signal.

Also, ICP.
That is bafflingly cool
