Weighing scales

What is the device?

These weighing scales are connected directly to the internet via Wifi, and send weight and body composition data to the minder platform.

Why is it part of the study?

The scales are used once a day by the participants to keep track of their weight, and hydration. Changes in weight can be an indicator of a health concern, and so when detected, the Minder monitoring team will recommend a clinical review or GP visit.

Hydration is also important for people with dementia, as they can sometimes forget to drink enough water. Dehydration can lead to greater levels of confusion, or be an indicator of a UTI.

How does it work?

The scales are connected to Wifi, and can send data automatically. The scales can recognise individuals by their approximate weight. To measure hydration, and other body composition measures, a small current is sent through the sole of the feet, and so must be used with bare feet (and not b y people with pacemakers fitted).

How is the device used in the Living Lab?

We use it in the lab to test the platform, including the Minder dashboard and app, and demonstrate the whole system to visitors. The scales do not work as well in the lab as participant’s homes, as the different weights of many different users on one device sets off many alerts!

Which teams are developing and using the device?

The monitoring and clinical team use the weight data to keep an eye on participants’ health and well-being.

Where can I find out more information about the device?

The scales we are currently using are made by Withings.
