As a key component of the OE, photonic integrated circuits (PIC) are predominantly realized on the silicon photonics (SiPh) platform, which provides CMOS-compatible fabrication, scalable heterogeneous integration, and the capability to implement full photonic functionalities on chip.

Furthermore, critical challenges and potential solutions for CPO system development are discussed, such as laser integration, thermal management, device reliability, bandwidth density, and energy efficiency.

This challenge is tackled by compositing tin sulfide (SnS) and graphitic carbon nitride (g-C3N4) through a controlled incorporation of g-C3N4 (0.5–15 wt.%), to modulate depletion width, band alignment, and surface defects. The optimized composite (1 wt.% g- C3N4, named SG-1) exhibits broadband absorption spanning 250–1400 nm, a strong zero-bias photocurrent (2.24 µA), and rapid rise/decay times of 0.48/0.47 ms, which are among the fastest reported for SnS-based photodetectors. Scanning Kelvin probe (SKP) analysis reveals a pronounced illumination-induced work-function modulation (ΔWF ≈ 0.23 eV), confirming enhanced built-in field and reduced surface defect density. Correspondingly, SG-1 achieves a responsivity of 2.8 mA/W and a detectivity of 1.9 × 109 Jones that is ∼4× greater than pristine SnS. The combined optical, electrical, and contact potential difference (CPD) establishes that g-C3N4-driven depletion modulation is instrumental for rapid carrier dynamics.

Scaling down electrohydraulic actuators, such as HASELs, from cm-scale to mm-scale requires a complete change in manufacturing methods, switching from laser patterning and film lamination to MEMS-like cleanroom processes. Here, we introduce a versatile wafer-level microfabrication strategy for soft electrohydraulic actuators at the millimeter and sub-mm scales. Scaling down such actuators leads to thinner films and hence to lower drive voltages but requires adapting MEMS processes optimized for rigid materials to be compatible with the polymers and liquid-filled cavities needed for electrohydraulics. Our wafer-level process integrates Parylene-sealed mm-long microcavities into multilayer architectures from flexible µm-thick polymer–metal layers. The resulting actuators operate below 300 volts, a substantial reduction from the 1–5 kV typical of similar macro-scale actuators. This microfabrication approach enables monolithic integration of actuators in robots, combining repeatability and precision. We realized a 20 × 20 mm2 sized swimming robot incorporating two embedded actuators to drive a pair of pectoral fins. This work establishes a pathway toward untethered electrohydraulic robots at millimeter scale and below.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"11 20","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.71249","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149235509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, numerous studies have focused on the fabrication and in vitro characterization of 3D-printed corneal substitutes, but fewer of them have evaluated their therapeutic efficacy in vivo.
