Here is my first post, it will handle the question: “Are young people the only ones that benefit of the technical improvements in sensor development?”.

After reading a blog over sensors that improves the live of the elderly, I got intrigued.

There are a lot of applications to help the elderly to improve their lives and those of their loved ones.
I read a paper about a tracking system for elder people to use in nursing homes. It’s a tracking system using ultrasound, you might say why not install a webcam in every room. Here I can immediately give you a few reasons, first of all the privacy of the patients, secondly this is a better way to store data about the whereabouts of the patients (examples: ‘time spent in bed’, ‘symptoms of frequent urination’).  It can also monitor when the patient does something which isn’t like the normal routine to trigger a ‘smart alarm’.
Maybe someone can give some other advantages?

In the paper they use a Wheelchair Locator (Ultrasound transmitter on wheelchair and ceiling full of receivers) and experiment with a Ultrasonic Radar Subsystem to detect the human head location (to signal when patients fall) with great success (experimental results are shown in the figure below).

So to conclude, we see that these sensors ease the job of caregivers, by preventing false alarms and not only alarming when an accident occurs but also preventing it.
