Important features:

1. Speed controller for consistent exertion of +/- force during extraction and pushing of liquid
2. Particularly useful for a viscous solution where initial plunger push may be uncontrolled
3. Has potential for self-administered diagnostics, medicine, etc. (i.e. EpiPen, places without doctors)

Concerns:

1. Do I make a completely new device or compatible with syringes already on the market?
2. Will it be using a battery or a charging wire?
3. How do I change the plunger size? Options include: Make a different device for each plunger (less efficient), Let one device have a variable/flexible plunger holder. How plausible is this design?, etc.

Sensor-based cane for people who are blind. I think I can potentially integrate a sensor similar to car's parking sensor.

For the lower limb (because it's most common). Some features to be mindful of: comfortable, sustainable, affordable, thermal sensing, etc.

After surgery, it's difficult for patients to move. This device would also be useful for people with amputation. This is somewhat similar to the drinking (Japanese) project Neil showed in class. Maybe I can include a heating feature to keep the food warm and a magentic cup for drinking as well.

Now that I have completed my final project, it's funny how none of these ideas ended up as my project. I also realized how difficult some of them are to achieve, especially as somebody who wasn't familiar with most of the tools I learned throughout this semester.
