GE Global Research has developed a non-contact monitoring system for prisons that aims to alert staff of a suicide attempt in progress. It works by tracking inmate’s movements and vital signs – but without the need for a wearable monitoring device! To achieve this the research team modified standard radar equipment to pick up the delicate movements of the chest caused by breathing and heartbeat.

The system which is designed to be mounted inside a prison cell could be an effective way to monitor at-risk individuals, without resorting to more expensive or more intrusive surveillance solutions. The US Department of Justice funded study proved to be 86 per cent accurate at determining whether someone required assistance.

The final technical report of the three part study is available in full at the National Criminal Justice Reference Service (NCJRS). GE is now exploring ways to commercialise the system in prisons and other settings. Read more: New ScientistNational Institute of Justice
