Innovative trio acknowledged by James Dyson Award

News

A pain-free home glaucoma test, a handheld scanner to identify plastics for recycling, and a device to stem blood from knife wounds have all been named winner of the James Dyson Award.

The three winners will each receive £30,000 to support the development of their inventions.

Students Kelu Yu, Si Li and David Lee from the National University of Singapore received their award for HOPES (Home eye Pressure E-skin Sensor), a wearable biomedical device for pain-free, low cost, at-home Intraocular Pressure (IOP) testing, which in clinical settings is a vital tool in helping doctors determine long-term treatment for glaucoma.

Powered by patent-pending sensor technology and AI, HOPES is described as ‘a convenient device for users to frequently self-monitor IOP.’

In use, the patient creates a profile in an App and then wears the HOPES glove with the sensor placed at the fingertip which is pressed against the centre of the eyelid. The fingertip is said to employ a unique sensor architecture that ‘captures dynamic pressure information of the user's eye with sub-millisecond precision’. The captured signals are processed by machine learning algorithms to continuously and accurately compute users’ IOP.
