A neuromorphic bionic eye with ultradense waveguide-coupled pixels and depth-adaptive optics enables high-fidelity 3D imaging and motion tracking for next-generation bio-inspired vision systems.

In-sensor spatial decoding enables single-step physical computation for fingerprint recognition, removing stored templates and delivering efficient, wave-based biometric authentication.

Stretchable complementary transistor amplifiers maintain stable gain under strain, enabling motion-robust, high-fidelity biosignal recording in soft bioelectronic interfaces.

Elastic organic electrochemical transistor amplifiers deliver strain-insensitive, high-gain in vivo signal amplification with a good signal-to-noise ratio through an integrated materials–device–circuit design.

Biosensors rely on biomolecular interactions for detection, and rigorous binding assays must therefore precede biosensor development. Conflating these two distinct measurements risks mischaracterizing biomolecules and propagating errors throughout subsequent biosensor design and interpretation.

A fibre-optic surface-enhanced Raman scattering pH sensor based on a polyprotic probe enables accurate underwater measurements across the full pH range and demonstrates stability and robustness for environmental monitoring under extreme conditions.

A cofactor-refreshing wearable lipid sensor continuously measures cholesterol and triglycerides in sweat, enabling long-term lipid tracking and supporting personalized lipid analysis with causal machine learning.

A butterfly-inspired polarization-sensitive vision sensor enables selective in-sensor processing and feature-specific imaging for accurate object recognition in cluttered environments with improved efficiency.

A phototransistor that couples fast charge trapping with slow ferroelectric polarization turns photocarrier lifetime from a fixed material parameter into a programmable hardware variable, enabling one sensor array to adapt its visual memory to motion across three orders of magnitude in speed.
