I’ll deliver a 45–60-minute, hands-on visit about my PhD, designing a pill-sized “smart capsule” for the gut that reuses parts from everyday gadgets (smartwatches/earbuds) to build a battery-free device that can sense pH/pressure/temperature, localize itself, communicate wirelessly by backscatter, and act by delivering medicine or collecting samples exactly where needed. I’ll bring 3D-printed capsule mockups, tiny inductive coils, a demo pump, and repurposed PCBs. A live demo will show an external coil lighting an LED inside a mock capsule to explain wireless power and why we avoid batteries; I’ll also give a simple, visual walk-through of how backscatter works and how multi-sensor data improves diagnosis. Students will stay involved through a short phone quiz and a quick design exercise: in pairs they choose a clinical “mission” and decide which three features they would include; we compare their designs with real engineering trade-offs, then wrap with Q&A.
This presentation directly answers your three questions.
(1) Research area/project: embedded electronics for an ingestible, battery-free capsule that combines sensing, localization, communication, and controlled actuation for diagnosis and therapy in the GI tract.
(2) Sustainability angle/relevance: repurposing consumer microelectronics reduces new manufacturing; eliminating batteries avoids hazardous materials; and designing for reuse/recycling supports circular take-back. Clinically, substituting some invasive procedures can cut waste, energy use, patient travel, and cost while widening access to advanced diagnostics.
(3) My path to DTU: I moved from high-school tinkering and student engineering projects to studies in electronics and embedded systems; a master’s thesis on real-time motor control gave me the hardware/firmware skills I now apply to health tech, which led me to a PhD at DTU Health Tech (IDUN/EMGUT) focused on making this capsule a reality. All demos are safe; I only need a projector and one power outlet.
