Self-Powered health sensors aim to transform dementia care

Developed by Surrey University spin-out Z-PULSE Ltd, the Self-Powered Tribo-Electric Pressure Sensor (STEPS1.0) allows for the advanced remote monitoring of essential indicators such as breathing patterns, bed occupancy, foetal movements during pregnancy and pressure distribution to avoid bedsores.

The sensors use the triboelectric effect to convert mechanical motion or pressure into electrical signals, enabling autonomous operation without external power sources

Furthermore, the technology is claimed to ‘seamlessly integrate’ into wearables, providing tailored solutions for specific healthcare needs while reducing maintenance and ensuring sustainable, real-time monitoring in applications that also include rehabilitation and sports performance analysis.

The shape, dimensions and sensitivity of the lightweight sensors can be customised also.

With £265,000 funding from Innovate UK, Z-PULSE is now working with the Surrey Sleep Research Centre, Kymira, and Milbotix to use STEPS1.0 in real-world healthcare settings.

Applications under development include continuous, real-time monitoring of sleep patterns, breathing and movement in dementia patients. Partners are also incorporating STEPS1.0 into a wearable belt that can detect foetal movements with the hope of preventing up to 3,400 stillbirths annually in the UK.
