Now, energy smart metres can monitor the activities of dementia patients in their homes. The device will track daily routines of patients when they boil the kettle, cook dinner or turn the washing machine on.
They will send alerts to family members when needed.
According to experts, the devices will enable patients to live independently for longer without going into care, and prevent avoidable admissions to A&E.
Ministers have promised to install the devices in every home by 2020 to reduce energy consumption.
Nearly, 850,000 people in the UK have dementia and this number is expected to double over the next 30 years as the population ages.
