Researchers Design Low-Power Sensor to Track Eye Pressure Changes

A team of engineers from the University of Washington has developed a low-power sensor that when implanted in a person’s eye can track changes in eye pressure, and transmit data wirelessly using RF waves. The sensor would allow ophthalmologists to monitor a patient’s eye pressure and proactively diagnose and treat glaucoma.

The device contains a thin, circular antenna that harnesses energy from the field to power a small sensor chip that monitors changes in frequency that correlate with changes in pressure.  The pressure changes are calculated, tracked, and recorded in real-time. The team is currently working to reduce the size of the device to fit in an artificial lens and making it affordable to patients.
