Dual Foreign Body Response Mitigation Strategies for Implantable Glucose Sensors

open access: yesAdvanced Sensor Research, EarlyView.
The foreign body response negatively impacts the analytical lifetime of implantable glucose sensors due to a heightened immune response and deposition of collagen. While nitric oxide release has shown promise as a foreign body response mitigation strategy, improvement is limited by the duration of release.

Modeling Electrical Transport in Random Networks Composed of Metal‐Oxide Nanowires: The Transition from Junction‐Dominated to Nanowire‐Dominated Regime

open access: yesAdvanced Theory and Simulations, EarlyView.
This study proposes a model for the electrical transport properties of random networks of metal oxide nanowires. Based on the characteristic lengths and energies of nanowires, it allows for discussing the transition from the junction‐dominated to the nanowire‐dominated transport regime.

A 3D Printing Strategy for Hard Curved Surfaced Circuits: From Materials to Applications

open access: yesAdvanced Science, EarlyView.
Conventional PCB etching (multi‐step) and indirect transfer techniques fail to meet structural electronics’ demands for lightweight, miniaturized, and customized manufacturing. 3D‐printed conformal circuits enable direct integration of conductive traces into substrates or onto surfaces, achieving integrated structural‐functional fabrication.
