Israeli company Hyginex has developed Digital bracelets to help reduce the risk of cross contamination around hospitals and other healthcare sites. Digtial bracelets work alongside sensor-embedded soap dispensers to detect if the user has washed his/her hands properly.
The bracelet has a tiny red LED light also to remind the medical practitioner to wash their hands between patients. The technology works via a wireless connection and the hygiene regime is tracked and passed on to hospital managers.
