Most devices are bulky and almost resemble old cellphones. This makes the device a burden to carry around and very non-discrete.

The smaller ones use Bluetooth which is also not healthy when it is being used 24/7. With the radiation going constantly through one’s body, it may not be great in the long run.

Based on these facts and more, this is our design criteria:

• For our device, we want it to be as small as possible, possibly connecting the transmitter and receiver together.
• It should also not rely on the insulin pump because while most patients have one, it should work on its own.
• It should be able to connect to the phone without constantly needing to use Bluetooth. Maybe a system that does not need the app on the phone to work. It should only use Bluetooth when necessary.

More specifically, these are the design criteria, with their justifications:

• Noninvasive: Invasive procedures are painful and lead to infection
• SMART Device Compatibility: Gets rid of the receiver and makes the phone the main receiver
  • Compatible with Bluetooth
  • More Detailed App Design
• Affordable: Not everyone can afford the device and it can be up to $1000
• Better Looking and Performing Device: There should be no shame in wearing the device and it should be concealed
  • Make more durable sensors without intruding on skin
  • Make more modern and sleeker looking transmitter
  • Making the monitor more accurate and close to glucometer results
