Bioelectronics: Wearable, Implantable, and Ingestible Systems

Yasser Khan. First edition, 2026.
ISBN-13: 979-8-9826941-0-2

Bioelectronic devices sit where electronics was never meant to go: on skin that stretches and sweats, inside tissue that attacks anything foreign, or in a stomach full of acid. This book explains how they are designed. It takes a sensing capsule, a wireless ECG patch, and a brain implant apart into the same blocks (body interface, sensor, front end, converter, processor, radio, power, and package) and then teaches each block in turn. Written for Bioelectronics, a graduate course at USC, it assumes no biology and no circuits beyond Ohm's law, so students from electrical engineering and from the life sciences can start together.

• Fourteen chapters, from cells and neurons to sensors, neural interfaces, soft materials, printing, power, and the path to patients
• Four labs that build one device layer by layer: a circuit board, printed electrodes, an analog front end, and firmware with a Bluetooth link
• Worked examples and problems in every chapter, with answers
• Color illustrations throughout
