Radar-on-Chip Biosensors
TIRESIAS
According to Greek mythology, Tiresias was a blind prophet of Apollo who, although sightless, could divine the future and possessed wisdom to guide those who would listen. Like its namesake, the TIRESIAS networked radar system provides deep insights into patient behaviour and disease progression.
Applications
COVID19 Social distancing monitoring
During the ongoing COVID-19 crisis we rapidly adapted the TIRESIAS system to aid with social distancing in our workspaces. In the video below, the system tracks the movements of the two people* sharing a bay in one of the NGNI Labs, emitting an alert sound when social distancing measures are being broken.
TIRESIAS: Social distancing with radar
*Disclaimer: the two people in the video are part of the same houshold.
CR&T (DRI): Care Research & Technology Centre (Dementia Research Institute)
For this project we will be using the TIRESIAS system to provide a range of metrics such as:
- Sleep monitoring (in collaboration with Surrey sleep lab)
- Walking speed and gait analysis (in collaboration with Saint George's University Hospital)
- Location and behaviour.
This information will help caring for dementia patients by allowing carers and practitioners to monitor changes in behaviour over time and deepen our understanding on how this desease progresses.
