Sensors in Socks and Smart Mattresses Are Helping Dementia Patients Stay Home Longer

A Home Transformed by Technology

There are sensors in every room of Jyoti and Bharat Patel's home. Their movements and habits are monitored constantly. But this doesn't worry them — in fact, it gives them peace of mind. For this west London couple in their 70s, a web of smart devices has become something most families caring for a dementia patient can only dream of: a safety net that doesn't require anyone to be in the room.

In 2019, Bharat started noticing that Jyoti was making uncharacteristic mistakes on stage during their magic performances. They were eventually given a formal Alzheimer's diagnosis in 2021. In 2023, they were approached by the team at the UK Dementia Research Institute and Imperial College London to take part in the trial, which is funded by the medical research charity LifeArc. Today, their home is a living laboratory — and a glimpse at what dementia care could look like for millions of families.

How the System Actually Works

Their house is now fitted with different sensors, connected via the internet, that send data back to a dedicated team of doctors, nurses, and other clinical specialists. That team uses the information to better understand how the person is managing their daily routine and identify early signs of changing health and care needs, with the hope of maintaining independence for longer.

The Patels' home is fitted with door sensors to detect nighttime wandering, kitchen appliances that monitor meal consumption, and a smart mattress that tracks heart rate, breathing, and sleep disturbances. Alongside the main trial, Jyoti is also testing out smart socks and a special watch that contain sensors to monitor her body temperature and keep track of any long-term changes in her gait — indicating frailty. Critically, none of the monitoring devices record video or audio, allowing medical staff to receive information on health trends without directly recording people inside their homes.

Running from October 2023 to October 2027, the "MinderCare" study utilizes a network of non-intrusive sensors to provide continuous, remote oversight. The system requires no action from the person living with dementia. That passive quality matters enormously — it means no burden is placed on the patient to remember to press a button or wear a device correctly.

The Cost Question

The couple is one of more than 250 families participating in the project by the UK Dementia Research Institute. Costs are expected to be about £2,000 a year, mainly to cover the monitoring and paying healthcare staff to analyze the data. If rolled out more widely, that could be a significant amount of money, with almost a million people living with dementia in the UK. But researchers push back on sticker shock.

Sarah Daniels, health and social care lead at the UK Dementia Research Institute, says the cost is no more than a couple of weeks in a care home. The main aim, she says, is to give earlier signals to health and social care professionals. Identifying subtle changes in a person's health could provide earlier signals for intervention, allowing clinicians and GPs to address medical complications or care challenges before they develop into emergencies.

A Model for the Future

The UK DRI Centre for Care Research & Technology, based at Imperial, is developing smart technology to support at-home care and allow people to remain at home for longer by identifying problems earlier. By harnessing artificial intelligence, the team has developed a unique, passive monitoring system that enables personalized care and support for people living with dementia. The technology is implemented into homes via Minder — the UK DRI's flagship digital care platform.

For Bharat, the value isn't measured in data points. He has said that even if the technology can cut down his worries by 5 or 10%, it helps him — and will help other people too. That's a modest ask for a system with potentially enormous reach. The hope is that the technology could be extended more widely across the health service, to reduce preventable trips to hospital and give families peace of mind. As dementia cases continue to rise globally, the question is no longer whether technology should play a role in care — it's how quickly it can scale.
