SAFARI is a biodegradable gelatin or cellulose pill casing with a radiofrequency chip that sends a signal confirming medication has been taken. The device could both change, and even save, the lives of patients who manage diabetes, have had organ transplants, or live with chronic infections such as tuberculosis or HIV. Not only can the smart pill be used to encapsulate medications, but its system can be built into existing capsules. This is not a device that will end up on drugstore shelves, since it is intended for patients whose lives hinge on taking their medication. “Future work includes development of battery assisted RFID systems to extend the detection range, further improving the application of the electronic medication adherence technology.”
