Photolithographic fabrication of biodegradable sensor arrays

Experimental approach
A photolithography-based microfabrication route for biodegradable flexible and stretchable sensors.
Key result
The paper reports up to 1600 fabricated devices within a 1 cm² footprint and functional passive, mechanical, and chemical sensor structures.
Scope and limitations
Fabrication feasibility does not alone define in vivo lifetime, tissue response, or clinical readiness.

Near-infrared-triggered degradation of transient electronics

Experimental approach
A molybdenum-mediated near-infrared heating strategy for a cyclic poly(phthalaldehyde) encapsulation layer.
Key result
The reported cPPA encapsulation degraded in about one minute, with rate controlled by laser power and exposure time.
Scope and limitations
Trigger penetration, thermal effects, geometry, materials, and biological context constrain translation beyond the reported configuration.
