OUR PROTOTYPING JOURNEY
PROTOTYPE #1
Our initial prototype was designed to test the feasibility of our components. We integrated six force sensors into a shoe insole. The sensors were connected to an Arduino board and six vibratory tactors. Each tactor vibrated at an intensity proportional to the force sensor reading.
PROTOTYPE #2
Our second prototype was designed to test the integration of the force sensors with a diabetic sock and assess the need for an outer casing to attach the force sensors to the sock. Although force sensor encasing was feasible, we ultimately decided to move forward by directly attaching the force sensors to the sock.
PROTOTYPE #3
Our third prototype was designed to test the device functionality after directly attaching the force sensors to the sock. After using silicone sealant to waterproof the sensors, we attached them to directly to the sock. We were able to get force readings from each sensor with this prototype.
FINAL CONCEPT ART
Our final product will consist of force sensors embedded directly into the sock. The sensors will be seamlessly connected with conductive thread to minimize force introduced to the bottom of the patient's foot. The arduino and power source will be detachable to ensure that the sock is machine washable. The vibrational tactor band will be removable as it is an optional component to be used based on patient preference and need.
