Spatially Configurable Conformal Sensor Integration on an Ultra‐Fine Metallic Needle for Minimally Invasive Deep‐Tissue Oxygen Monitoring

Advanced Materials Technologies, EarlyView.
A multi‐point oxygen‐sensing ultra‐fine needle (MO‐UFN) is developed by conformally integrating a lithographically patterned flexible electrochemical sensor array onto a clinical acupuncture needle. The platform preserves an approximately 0.3 mm diameter while enabling spatially resolved oxygen profiling along the insertion pathway.

Microscale 3D‐Printed Digital Strain Switches for Embedded Mechanical Computation

Advanced Materials Technologies, EarlyView.
Microscale 3D‐printed strain switches on flexible films convert deformation into native digital signals at geometry defined thresholds. A closed form model predicts switching from 3000 to 15 000 microstrain and is validated across 110 devices. Reliable ohmic closure and strain activated AND, OR, and XOR logic point toward low‐power mechanical ...

Turning Light Into Matter: Programmable Microstructures Via Dose Control in Two‐Photon Polymerization

Advanced Optical Materials, EarlyView.
This work augments two‐photon polymerization with point‐wise dose control, enabling structures with heterogeneous material properties such as refractive index. An open source toolbox and superior calibration methodology for the refractive index pave the way for bio‐mimicking or numerically optimized structure designs, and enhance the synergy between 3D
