Observational StudyA novel ingestible electronic drug delivery and monitoring device.
We developed an ingestible electronic drug delivery and monitoring system. This system includes an electronic capsule comprising a drug reservoir, a pH and temperature sensor, a microprocessor and wireless transceiver, a stepper motor, and batteries. The location of the capsule in the gut derived from pH data can be monitored in real time. The stepper motor can be remotely actuated to expel the contents of the drug reservoir. ⋯ This electronic drug delivery and monitoring system may be a promising tool for targeted delivery of substances to well-defined areas of the GI tract.
