Smart socks helping protect people with dementia

A university PhD student has invented ‘smart socks’ which sense when people with dementia and autism are in distress.

Dr Zeke Steer wanted to help after seeing his great-grandmother suffering with dementia.
The socks, which track heart rate, sweat levels and motion, enable carers to intervene before things escalate.
Dr Steer worked at Bristol Robotics Laboratory to find a solution and develop a mobile phone app.
Current alternatives are worn on wrist straps, which have been found to stigmatise patients or even cause more anxiety.
