What if medical electronics could become virtually invisible – not only conforming seamlessly to the human body but also sensing, communicating, and even interacting with living tissues? Recent advances in graphene and other two-dimensional materials are making this vision possible by enabling a new generation of wearable, implantable, and intelligent bioelectronic systems. Their unique combination of atomic thickness, flexibility, transparency, electrical conductivity, and biocompatibility is fundamentally changing how electronics interface with biology.
In this talk, I will explore how these materials are enabling technologies that were previously impossible. I will introduce graphene electronic tattoos that laminate onto the skin like temporary tattoos to provide long-term, high-fidelity monitoring of electrophysiological, mechanical, and biochemical signals. Applications will include continuous cuffless blood pressure monitoring using bioimpedance, multimodal physiological sensing, and wearable biosensors capable of tracking biomarkers directly from sweat. Beyond the skin, I will discuss the translation of these ultrathin biointerfaces into implantable devices, including transparent graphene arrays for recording and stimulating the heart. These tissue-conformable interfaces enable simultaneous electrical sensing, optical imaging, and optogenetic modulation while opening new opportunities for minimally invasive therapies and next-generation bioelectronic medicine. Finally, I will present our recent work on graphene-based neuromorphic devices that emulate the adaptive behavior of biological synapses with energy efficiencies approaching those of neurons. These systems represent an important step toward intelligent bioelectronics capable of learning from physiological signals, enabling adaptive biosensing, closed-loop therapeutics, and future human–machine interfaces. Together, these examples illustrate how atomically thin materials are driving the shift from rigid electronic devices to bioelectronic systems that integrate naturally with living tissues.
