Description
Ingestible medical devices are revolutionizing biomedical diagnostics and therapeutics in applications such as endoscopy, biosensing, and tissue stimulation. Wireless radiofrequency RF communication – essential for real-time data transfer and control of these devices – faces challenges with strict specific absorption rate limits, implant size restrictions, and the high loss of biological tissues, resulting in tight link budgets. We introduce herein a comprehensive link budget assessment method for ingestible radiofrequency devices for evaluating link loss and efficiency across the digestive tract and present a smart capsule case study to demonstrate its effectiveness in determining the required radiated power and optimizing external receiver placement.
