Time-Dependent Color-Changing Vaccine Reminder Ankle Bands

Noor Sabah Rakhshani of the Trust for Vaccines and Immunization in Pakistan proposes to develop children's polymer ankle bands incorporating electrochemical indicators that change color at specified time intervals to remind mothers of their childrens' vaccine due dates. This low-cost technology would work well in areas where SMS/text reminders are not feasible due to limited cell phone coverage and lack of funds for cell phone hardware and accounts.
