In order to determine how a patient is recovering from orthopedic surgery, doctors must presently rely on technologies such as X-rays or MRIs. Before too long, however, they may instead simply be able to read the output from tiny sensors, implanted in the patient's body. A team of scientists from New York's Rensselaer Polytechnic Institute have already created prototypes of just such a device, that measure a mere four millimeters across and are 500 microns thick.
