---- PROTOTYPE --------- PURPOSE: To create a prototype of seizure monitoring and response transducer for individuals with seizure disorders to alert their assigned caretaker for assistance. As part of their senior design project, Rice University students Ethan Leng, Mihir Mongia, Charles Park, and Tiffany Varughese created the Seizure Monitoring and Response Transducer (SMART) Belt to combat the complications of seizures by alerting caregivers to seizure activity. The students worked with Andrew Wu of Cyberonics Inc., a Houston-based medical device company (project sponsor), and Gary Woods, a Rice professor in the practice of computer technology and electrical and computer engineering (project advisor). The SMART Belt monitors the user for signs of epileptic seizures and alerts the user's caregiver(s) in case of a seizure. The SMART Belt combines a respiration sensor and an electrodermal activity (EDA) sensor to detect increased electrical conductance in the skin and changes in respiration rate, both signs that a seizure is underway. Children or adults can wear the belt. According to the designers, the belt is targeted for children six years and older. When the sensors detect signs of a seizure, the transmitter sends data via Bluetooth to either a computer or smartphone. The students aspired to create an inexpensive, comfortable device that could be worn around the clock under a patient’s clothes and not only monitor for seizures but also compile a record of seizure occurrences that would be of value to their doctors. As part of testing with healthy subjects, volunteers were asked to hyperventilate or they were startled by a loud noise, both of which prompt a "fight-or-flight" response similar to what a person with epilepsy experiences during a seizure. The students see their device as a way to help many of the 2.3 million people with epilepsy in the United States. While the SMART Belt will not prevent or arrest a seizure, it serves as an early warning device to assist parents in keeping their children safe and stable.
