| Abstract Scope |
Rapid advances in additive manufacturing and printed electronics have created a demand for sustainable, biocompatible materials that can be processed at low temperatures while delivering robust sensing and energy-harvesting functions. We report a family of biomass-derived triboelectric nanogenerators (TENGs) that are formulated as printable inks based on lignin and chitosan biopolymers. Using low-viscosity, water-processable formulations and sintering-free drying below 80 °C, we pattern conformal, multilayer TENG structures directly onto flexible substrates, as well as onto 3D-printed elastomeric surfaces.
The printed devices achieve power output sufficient to drive low-power Bluetooth® beacons or on-board microcontrollers without external batteries. Pressure-mapping modalities enable continuous, non-invasive monitoring of pulse wave velocity and joint kinematics. Our results demonstrate (i) ink-to-device workflows that align with roll-to-roll and direct-write printing paradigms, (ii) compatibility with porous or biodegradable substrates for transient electronics, and (iii) a clear route toward scalable manufacturing of multimaterial, multifunctional structures for wearable healthcare. |
