Systematic experiments and fluid dynamic simulations evaluated the influence of applied voltage, wind speed, windward angle, and geometry. The BCS achieved a peak collection rate of 390 mg/min at 18 kV and a wind speed of 2 m/s, representing a substantial enhancement over passive designs. Furthermore, the performance of longitudinal and radial BCS arrays was quantitatively analyzed, leading to a modified saturation model that accounts for airflow interference between adjacent units. The results further determine the optimal working parameters and array layout, which can parametrically adjust aerodynamic airflow regulation and improve droplet transport efficiency.

However, achieving efficient NIR absorption and high photodetection sensitivity simultaneously remains a significant challenge for most organic semiconductor systems. Here, a high-performance hybrid organic phototransistor is developed by combining a PBTTT-C14/F4-TCNQ donor–acceptor charge-transfer complex with monolayer graphene. Strong intermolecular charge-transfer interactions generate low-energy electronic transitions, resulting in broadband optical absorption spanning 400–1300 nm. Meanwhile, the incorporation of graphene provides an efficient transport pathway for photogenerated carriers and promotes charge separation, thereby enhancing photoconductive gain. As a result, the hybrid device exhibits excellent NIR photodetection performance under 800 nm illumination, delivering a responsivity of 1.67 × 105 A/W, a detectivity of 3.26 × 1012 Jones, and an external quantum efficiency of 2.92% × 107%. Notably, a measurable photoresponse is maintained even under extremely weak irradiation, demonstrating outstanding sensitivity toward low-intensity optical signals. In addition, the device shows stable switching behavior with millisecond-scale response characteristics. Integration into a phototransistor array further enables spatially resolved NIR imaging.

Biodegradable and transient electronics have emerged as promising solutions by enabling controlled degradation and material recovery. Chitosan, a widely abundant biomaterial derived from chitin, has attracted significant attention due to its biocompatibility, biodegradability, and versatile chemical functionality. These properties enable its integration across multiple electronic components, supporting the development of fully or partially biodegradable systems. Chitosan has been widely employed as a dielectric layer in transistors, an ionic conductor, a transparent flexible electrode, and as a host or scaffold in electronic devices. Despite extensive research, existing reviews typically focus on specific applications or broader material classes, leaving a gap in understanding how chitosan can be systematically integrated into complete electronic architectures. This review provides a comprehensive and structured analysis of chitosan's properties and its integration into key device components, including electrodes, transistors, memory devices, optoelectronics, energy systems, and scaffolds.

By merging dominant traits from parent geometries in the latent space, our approach enables deterministic latent optimization, yielding a high prediction accuracy for energy (R2 = 0.957) and force (R2 = 0.981).

Experimental validation using additively manufactured thermoplastic polyurethane (TPU) lattices confirms that DLH-optimized architectures exceed the performance of their base designs, achieving up to 24.03 J of absorbed energy and a peak force of 9.80 kN.
