My Comments
A 16-year-old had developed a device which alerts someone else if a person like an Alzheimer’s patient wanders out of bed. This boy, Kenneth Shinozuka, was inspired to develop this device because of an incident where he was out with his grandfather at age 4 and Grandpa wandered off and was lost. Here, this brought to his family’s attention that Grandpa had Alzheimer’s disease.
A situation that was very common for him and his family was that his aunt who was his Grandpa’s primary carer wasn’t sleeping properly because she worried that if she slept, he would climb out of bed and wander absent-mindedly.
Here, he designed the device to be attached to the patient’s sock, slipper or foot to sense foot pressure associated when they climb out of bed to start wandering. This device uses a Bluetooth Smart (Bluetooth Low Energy) link to a suitable smartphone that is equipped with an “alarm” app that audibly alerts the carer and shows up a timer to show how long they have been off the bed. There is the ability to set up a threshold and a “hold time” so as to allow for situations like the patient going to the bathroom at night to do what he has to do.
He developed this device through a few science fairs including the Google Science Fair where he got the respect and was given the Google Science Fair Global Finalist prize amongst a few other awards. Scientific American and Popular Mechanics, both respected science and technology magazines even gave him awards for this device. He was able to use the prototype with his Grandpa and his aunt in this situation and she was able to claim a lot more sleep each night because of not worrying if he was about to get the wanders overnight.
Kenneth saw this as being important for the “ageing at home” phenomenon where older people are staying at home in the care of family members and friends rather than going in to care at nursing homes or similar facilities. He is evolving the technology towards other aspects of this phenomenon like a bathroom floor that senses if someone is falling and a medicine box which alerts the older person to take their pills at the right time.
