Montreal-based 9th-grader Aviana Machnes didn’t only come up with an award-winning science fair idea, she created a device that could save the lives of dementia patients. It all started with a pot left out on the stove.
As reported by Global News, Machnes’ grandmother, who has early-onset dementia, had forgotten to take a pot off the hot stove, subsequently leaving it there overnight. Finding no solutions to this problem, Machnes decided to tackle it herself.
Using current sensors and motion detectors, Machnes created a device dubbed the Forget-Me-Not that will automatically set off an alarm if no one is around for an extended period of time.
This not only earned Machnes a top placement at her regional science fair (beating out older students) but it’s now something she hopes to patent (along with a phone app) that would be implemented into long-term care homes.
The invention is something that Jesse Clair, one of Machnes’ science teachers, calls a great example of how, even in a school environment, students can “get their hands dirty” to “work on actual real-world problems.”
A growing need for everyday safety solutions
Machnes’ device taps into a very real and increasing need. Dementia affects millions of people worldwide, and one of the most pressing concerns for families and caregivers is safety in the home when individuals are left without supervision. Everyday tasks like cooking can become dangerous when memory lapses occur. Devices like the Forget-Me-Not aim to bridge that gap, offering a layer of protection without taking away independence.
Other innovations are addressing similar concerns. Smart stove shut-off systems, for example, can automatically turn off burners if no movement is detected nearby. Wearable GPS trackers help caregivers locate loved ones who may wander. Some companies have even developed simplified communication tablets designed specifically for those with cognitive decline, allowing users to connect with family through easy-to-navigate interfaces.
Breakthroughs in dementia research
Beyond assistive devices, scientific research is making unprecedented progress in understanding and treating dementia. In recent years, new medications and lifestyle changes have been developed that may slow cognitive decline in patients with early-stage Alzheimer’s disease. In some cases, these changes may even prevent it entirely.
Similarly, advancements in brain imaging have improved early detection, giving patients and families more time to plan and seek treatment. There is also growing interest in personalized care approaches, which tailor therapies to an individual’s specific condition and history.
When science fair ideas change lives
Science fairs have long been the starting point for inventions just like Machnes’ that later found real-world applications. One well-known example is a student-designed early warning system for heart attacks that used simple sensors to detect irregular patterns. Another young inventor created a low-cost water purification system that has since been adapted for use in communities lacking clean drinking water.
These projects often begin with a personal experience, much like Machnes’ story. A problem at home or in the community becomes the catalyst for experimentation. With guidance from teachers and access to basic tools, students can transform these creative ideas into tangible solutions. It really is a team effort.
