ode is a fragrance-release system designed to stimulate appetite among people with dementia. The mains-powered unit releases three food fragrances a day, adjustable to coincide with the user’s mealtimes.

Weight loss is common to most people with late-stage dementia and can be an early indicator of the condition’s onset.

This discreet system is less stigmatising and more inspiring than an alarm or constant reminders from carers to eat. Initial research suggests it can stimulate real hunger subliminally. Scents are pleasant and evocative, and aim to improve mood as an additional effect.

The prototype for ode was developed as part of a joint competition, run by the Design Council and the Department of Health, to find teams of designers and experts who could develop new ideas to help improve the lives of those affected by dementia.

Scents have been developed specially for ode, in conjunction with a leading fragrance laboratory and in response to workshop feedback. Users can choose their preferred scents at installation.

Fragrances are released in short sharp bursts, acting as a strong appetite trigger and then dissipating rapidly so users won’t become inured to the effect.

A subtle light indicates the device is working and also communicates when fragrances need refilling.
