The sensor could monitor and wirelessly transmit data regarding load, strain, motion, temperature, and pressure
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 a prototype of just such a device, that measures a mere four millimeters across and is 500 microns thick.
The sensor requires no wires, batteries, or telemetry within the body. The idea is that it would be attached to a conventional orthopedic implant, which would then be installed as it normally would be, within the body. After that point, the sensor could monitor and wirelessly transmit data regarding load, strain, motion, temperature, and pressure, from the site of the implant.
This data could allow doctors to determine when it was safe for the patient to return to work, and could also alert them to problems with the implant.
