Purdue University innovators are developing inventions that use microchip technology in implantable devices and other wearable products, such as smartwatches, to improve biomedical devices, including those used to monitor people with glaucoma.

The Purdue team developed a fully implantable radio frequency transmitter chip for wireless sensor nodes and biomedical devices. The transmitter works in a similar fashion to communication technology in mobile phones and smartwatches, but the Purdue transmitter has such an unprecedented level of miniaturization and low-energy consumption that it can be implanted into an eye to monitor pressure for a glaucoma patient.

The transmitter facilitates a wireless communication between the sensor node or biomedical device and a smartphone application. The user can simply operate the device through a smartphone application and receive the biophysiological data in real time. The transmitter in this case enables a 24-hour intraocular pressure monitoring for glaucoma patients, which has significant implications for optimizing the management of glaucoma.
