Scaling up such hardware is key to enhancing its application in edge artificial intelligence platforms. However, development has been limited due to a trade-off between weight precision and energy efficiency: methods to increase weight precision (such as using elevated operating voltages to encode other conductance states or using calibration and compensation schemes to mitigate device-to-device variations) are effective at improving performance but are energy intensive. Here we report on an in-hardware signal-folding scheme that can provide both high weight precision and high energy efficiency. The approach uses two folding schemes—input signal folding and weight conductance folding—to predefine signals applied for vector–matrix multiplication, and we implement the schemes using a vertical one-transistor–one-resistor MoS2 crossbar array. In both schemes, the signals are encoded into two combinatorial folded signals. The input signal folding decreases the operating voltage, whereas the weight conductance folding circumvents device-to-device variations to expand weight precision. Compared with computing with the unfolded signal, our method can reduce the power consumption of vector–matrix multiplication by up to 90%, while achieving similar accuracy and without calibration or compensation schemes.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"41 1","pages":""},"PeriodicalIF":34.3,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional wet-transfer processes used to integrate the materials onto flexible substrates often introduce surface contamination that degrades device performance. Here we report a wafer-scale dry-transfer strategy based on a high-κ dielectric aluminium oxide (Al2O3) interlayer, enabling the integration of 4-inch single-crystalline molybdenum disulfide (MoS2) films onto flexible substrates. The approach requires no contact with polymers or solvents, thus preserving the intrinsic electronic properties of the MoS2. Flexible field-effect transistor arrays fabricated using this method exhibit a maximum mobility of 117 cm2 V−1 s−1, subthreshold swing of 68.8 mV dec−1 and on/off ratio of 1012, comparable to values achieved on rigid substrates. We further demonstrate MoS2-based flexible inverters operating in the subthreshold regime with a gain of 218 and power consumption of 1.4 pW µm−1. Finally, we integrate an active-matrix tactile sensing system driven by flexible MoS2 transistor arrays onto a robotic gripper, providing real-time tactile mapping and object recognition.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"69 1","pages":""},"PeriodicalIF":34.3,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite recent developments, achieving a microscale optical dispersion component that can deliver multiple spectral responses without applying external stimuli remains difficult. Here we show that ultrafast-laser-induced micro-vortices in polycarbonate substrates can be used to generate intricate dispersion signals at the microscale. The approach, which is based on the photoelastic effect, can provide rich and varied spectral responses for efficient sampling. The dispersive structures operate over a broad bandwidth (400–1,550 nm), occupy a compact footprint (10 × 10 µm2) and are independent of the viewing angle. The approach is also applicable to different thermoplastic polymers and is robust against harsh conditions. We show that the micro-vortex structures can be integrated with an image sensor for on-chip spectral analysis and high-resolution microscopic spectral imaging.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"145 1","pages":""},"PeriodicalIF":34.3,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147734068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By covalently embedding a high-performance n-type polymer semiconductor inside an elastomer matrix, we fabricate fully stretchable transistors with electron mobilities of 0.28 cm2 V−1 s−1 under 100% strain. Furthermore, with a covalent functionalization strategy on the p-type polymer semiconductor layer, we demonstrate successive, direct photo-patterning of n-type polymer semiconductors without electrical degradation on the existing p-type.

However, many people suffer from blindness due to retinal diseases that cause photoreceptor degeneration. Electrical stimulation of retinal neurons can recreate the action potentials associated with seeing that are generated by these cells. Here we report a thin artificial retina that can be adhered to the epiretinal surface and can convert near-infrared (NIR) light into electrical stimuli that selectively stimulate ganglion cells. The artificial retina consists of a NIR-sensitive phototransistor array and three-dimensional liquid metal micropillar electrodes. The liquid metal electrodes enhance proximity to retinal ganglion cells, providing effective charge injection while minimizing tissue damage, owing to their low Young’s modulus. Ex vivo studies demonstrate its biocompatibility, and in vivo studies using healthy and blind mice demonstrate perception of both visible and NIR light, as indicated by cortical recordings and behavioural tests. The retina could, in the future, be used to create a NIR visual channel in patients with photoreceptor degenerative blindness without interfering with their remaining natural vision.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"11 1","pages":""},"PeriodicalIF":34.3,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147685147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
