In summary, a universal EGaIn‐based DIW printing strategy is presented for fabricating wideband stretchable antennas. The printed antenna achieves an operating bandwidth of 3.75–8.21 GHz (fractional bandwidth: 75%), a peak gain of 1.8 dB and a radiation efficiency of 76.6%, surpassing state‐of‐the‐art stretchable antennas. More importantly, the antenna

Pupil‐Adaptive Retina Projection Augment Reality Displays With Switchable Ultra‐Dense Viewpoints
This paper presents a seamless retina projection AR display with 49 switchable ultra‐dense viewpoints, achieving a record high rotation precision of 1.28°/viewpoint. With a light selector, only a singular image can be consistently perceived by eye‐tracking without image missing or overlapping regardless of dynamic pupil under different ambient lights ...

Hyperbolic Topological Quantum Sources
In this work, we present the experimental realization of hyperbolic topological quantum sources on silicon chips, which only require fewer resources to achieve a higher brightness. It shows a high utilization efficiency and a strong robustness. Abstract Robust Integrable Quantum Optical Sources, Constructed by Topological Boundary States, Are Crucial ...

A near‐infrared tunable micro‐spectrometer is achieved by integrating a PbS photodetection unit and a light modulation unit based on liquid crystal tuned optical resonances, demonstrating a wavelength tuning range exceeding 850 nm. This micro‐spectrometer shows high fidelity in spectral reconstruction and is also successfully applied to plastic sorting,
