MotionDx: Creating an Effective and Affordable Smart Pill Bottle

Non-medication adherence causes hundreds of billions of dollars to be lost across the world every year. Numerous pill organizers have been created, especially for patients with faulty memory, such as the weekly pill container. Many patients found these a hassle to refill and use, so companies began to create smart pill bottles that would remind the user periodically throughout the day to take their medicine. These expensive models incorporated high-tech features and yet were still ineffective. This innovation aimed to create a smart pill bottle that will help users take their medicine on time and allow them to view their adherence statistics, all while keeping it easy to use and the cost affordable.
An analysis of different smart pill bottles currently known to the public was conducted. These bottles were tested for their cheapest and best features, to create the ideal affordable design. The product would be built for casual daily-use patients at a low cost so that it was accessible to any patient that needed help with their adherence. Numerous sensors were researched and tested to find the cheapest method for completing the goal. Arduino UNO was used as the microcontroller to process and run the code, written in c++. MIT App Inventor 2 was used to create a companion app for the bottle, where the user can store their compiled dose data retrieved from the Arduino board and view it in multiple forms.
The final product implements a motion sensor to detect when the user passes, meaning that it will only remind the user by sounding a short buzz when they are within proximity, making taking medicine as easy and convenient as possible. It uses a limit switch placed on the inside of the cap to detect when the cap is opened to track doses. After the user has taken their dose for the given time period, the device will save the exact time it was taken, then will shut off and not remind until the next dose is needed. It will also lock the bottle via a servo motor inside the cap that will contact a magnet when a dose is not needed, preventing the user from accidentally taking unnecessary doses. All components for the product can be bought for under $25— a price that could be well-reduced as it is still an Arduino-based prototype— which is much more affordable when compared to the other bottles available on the market that are being sold for $100 or more.
