Four Purdue University engineering students placed in the annual Texas Instruments Innovation Challenge for their project, TrackRx, taking home the "best use of TI wireless technology" award. The students stand out among the nearly 180 teams that competed this year. TrackRx is a wireless, internet-connected pill bottle designed to make it easier for patients to take their medication correctly and harder for them to abuse prescription medications by dispensing a single dose at a time and providing data to the patient's pharmacist, doctor and other caretakers. Along with the pill bottle itself, the TrackRx system consists of an Android app for the patient, a desktop application for the pharmacist and doctor, and a database and cloud service to communicate with the bottle and applications and securely store patient information. The students, who carried out the project as undergraduates, were team leader Jacob R. Stevens, a computer engineering major from Crestwood, Ill., who is entering a Purdue doctoral program; team members Erik Swan, an electrical engineering major from Eden Prairie, Minnesota, who has graduated; Manik Singhal, an electrical engineering major from New Delhi, India, who is entering a Purdue graduate program; and Everett Berry, a computer engineering major from West Lafayette, who has graduated. Matthew Swabey, deputy director of instructional laboratories in Purdue's School of Electrical and Computer Engineering, advised the students.
