For our second prototype, we changed appearance of our product and made it look like a protection brace.

The picture below is what our second prototype looks like.

We attached the whole circuit into a 3D printed box that provides protection to the fragile wires, Arduino, breadboard, and battery. By keeping the circuit same as the last prototype, we sew those two flex sensors on both lateral sides of an ankle brace so that they can detect the angle between user’s foot and lower leg. We put the vibrator on the middle of the brace as the picture shows.

The second prototype has all the function we want for now. It is actually wearable and able to detect user’s movement. We only need to improve it by making the brace looking neater and more durable.
