Swallowable sensor transmits live reports on intestinal glucose levels

“Currently in development at the University of California-San Diego, the pill is essentially a combined biosensor and biofuel cell, housed within a 3D-printed polymer shell. Once ingested, it continuously measures glucose levels in the small intestine, plus it uses that same glucose as fuel.  At regular intervals, the pill wirelessly transmits its readings using an energy-efficient technique known as magnetic human body communication. In a nutshell, this involves sending ultra-low-power magnetic pulses through the patient’s body tissue, which are detected and decoded via a receiver-coil-equipped device worn on the outside of the body.”    MORE
