In my opinion, I believe that your senior design product would be considered as a mobile medical app. In the week 1 lecture, we learned that Medical Device is anything that cure, prevent, or treat disease in humans. Furthermore, your device aids people with hearing loss and therefore it is considered as “mobile medical app”. After doing further research on medical apps, I found this really interesting app called “iHealth”, which measures all your vitals as well as your sleep. This device has really interesting analytics and graphs for all the vitals, which is really helpful for elderly in understanding their personal health. It is really interesting to see where technology has taken us and what the future will be?
