While neuromorphic bio-inspired devices present a promising alternative, their typical dependence on charge trapping and de-trapping mechanisms often constrains response speed and limits their applicability in low-power, real-time motion perception scenarios. In this study, we develop a functionally retina-inspired optoelectronic sensor based on two-dimensional γ-InSe, where engineered interlayer sliding enhances spontaneous polarization. Leveraging the photo-pyroelectric effect under zero-bias operation, the sensor emulates the visual adaptation functions of the snake retina. Configured as a 5 × 5 array, it achieves integrated spatiotemporal perception over a broad spectral range (400–1100 nm), enabling all-day motion tracking. The sensor exhibits a rapid response time of 37.4 ms, a wide dynamic range of 103 dB, and reliable decoding of motion trajectories under varying illumination—all in a self-powered mode. When integrated with a neural network, the system achieves simultaneous inference of multiple target parameters, including direction, velocity, ambient lighting conditions, and rotation, achieving trajectory recognition accuracy exceeding 99.6%.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"8 9","pages":""},"PeriodicalIF":19.6,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.70166","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148823194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inspired by this principle, we report a rhodopsin-mimetic photovoltaic dual-transistor (PVT²) photosensor cell integrating a quasi-2D perovskite photodiode with dual IGZO thin-film transistors. By electrically regulating light-induced charge accumulation and release, the PVT² device enables adaptive operation spanning scotopic and photopic regimes. The device exhibits a responsivity of up to 139 A W^–1, a photo-to-dark current ratio exceeding 10⁷, and a tunable recovery time down to 10⁻³ s, relaxing the trade-offs among responsivity, photo-to-dark current ratio, and recovery dynamics. At the array level, PVT² sensors autonomously maintain high image contrast under fluctuating ambient illumination while suppressing inter-pixel crosstalk. Beyond imaging, the light-intensity-dependent operating window functions as a reconfigurable hardware key, enabling single-band visible-light communication with accurate decoding and quantifiable per-symbol entropy.

Chiral organic small molecules have emerged as attractive active materials due to their structural tunability, well-defined intrinsic chirality, and solution processability. However, in most chiral organic small molecule systems, molecular-scale effects and optical selection rules lead to mismatch in magnitude and spatial orientation between the magnetic and electric transition dipole moments, resulting in low absorption dissymmetry factors (<i>g</i>_abs) and poor compatibility between chiroptical response and charge transport. This review summarizes the recent progress in chiral organic small molecules for CPL detection from the perspective of group theory. By comparing the representative chiral point groups such as <i>C</i>₁, <i>C</i>_n, and <i>D</i>_n, we elucidate how point group symmetry imposes constraints on the relative arrangement of transition dipole moments, thereby governing the molecular <i>g</i>_abs. In particular, the <i>D</i>₂ point group can enforce both electric and magnetic transition dipole alignment along the principal molecular axes, yielding an optimal orientation (0° or 180°) and thus enabling the high <i>g</i>_abs. Recent advances in chiral organic small molecules <i>D</i>₂ point group demonstrate their potential to simultaneously achieve strong chiroptical responses and efficient charge transport, offering a clear structural guideline for the rational design of high-performance CPL photodetectors based on chiral organic small molecules.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"8 8","pages":""},"PeriodicalIF":19.6,"publicationDate":"2026-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.70155","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By employing a composition pinning growth (CPG) strategy, the formation of segregation-prone crystallization states is suppressed, leading to reduced surface Sn enrichment and Sn oxidation, lower defect density, and more favorable charge-carrier dynamics. As a result, CPG-based devices achieve power conversion efficiencies (PCEs) of 19.37% at the unit-cell level, among the highest of reported all-inorganic Pb-Sn PSCs, and 17.03% for 64 cm² aperture area modules and enhanced operational stability, retaining approximately 87% of the initial efficiency after 1000 h of continuous operation at 85°C and 85% relative humidity.

However, it remains challenging to combine these sensor performances due to inherent property trade-offs in pressure-sensitive ion-conducting elastomers (ICEs), particularly among mechanical resilience, softness, and ionic conductivity. To address this issue, we propose a load-bearing and mechanically reversible network design that integrates strong covalent crosslinks for mechanical elasticity, weak sacrificial bonds for softness, and dynamic coordination interactions to facilitate ion transport. Based on this strategy, our fabricated ICEs exhibit excellent elasticity (&lt;5% hysteresis over 1000 tensile cycles), low elastic modulus (~66 kPa), intrinsic self-healing capability, and high ionic conductivity (2.57 × 10⁻⁴ S cm⁻¹ at room temperature). The resulting iontronic sensor achieves high sensitivity (8.28 kPa⁻¹), low detection limit (6 Pa), and minimal signal drift (~0.72% capacitance change over 10 h.). Finally, the superiority of the low drift iontronic sensor is demonstrated by a robotic gripper with high reliability.
