Wearable and implantable bioelectronics have emerged as transformative tools for health monitoring, diagnosis, and therapy, moving from bulky and rigid devices toward soft, tissue‐integrated devices for daily use. However, existing systems in the form of wearable patches (or implanted devices) often remain mechanically rigid, creating a mismatch with soft biological tissues and introducing artifacts from relative motion at the tissue-electronics interface. In this lecture, I will present the development of two distinct classes of soft bioelectronics – wearable and implantable – designed to overcome these limitations.

The first platform is ultra‐conformal, customizable, and deformable Drawn‐on‐Skin (DoS) bioelectronics. Fabricated in situ using liquid electronic inks, DoS devices intimately interface with the skin to minimize motion artifacts without additional hardware or computation. Their fabrication simplicity and versatility enable rapid deployment of multifunctional devices tailored to individual anatomies. The second platform focuses on rubbery cardiac bioelectronics that match the mechanical softness of heart tissue while enabling multiplexed ECG mapping, strain and temperature sensing, electrical pacing, thermal ablation, and energy harvesting. These devices maintain stable electrical performance while deforming with a beating heart, offering a stable system for high‐fidelity cardiac monitoring and intervention.

As another implantable bioelectronics platform, I will also introduce an optoelectronic bioink system for creating light‐responsive hydrogels. By integrating microscale solar cells into 3D‐bioprinted scaffolds, this approach enables wireless, minimally invasive optical modulation of cardiac tissue without genetic modification. Together, these advances illustrate a path toward bioelectronic systems that seamlessly integrate with the body’s natural mechanics, providing robust, personalized, and multifunctional platforms for next‐generation healthcare.
