Analogue memristors with multiple conductance states are of particular use in high-efficiency neuromorphic computing, but their weight mapping capabilities are typically limited by small on/off ratios. Here we show that memristors with analogue resistive switching and large on/off ratios can be created using two-dimensional van der Waals metallic materials (graphene or platinum ditelluride) as the cathodes. The memristors use silver as the top anode and indium phosphorus sulfide as the switching medium. Previous approaches have focused on modulating ion motion using changes to the resistive switching layer or anode, which can lower the on/off ratios. In contrast, our approach relies on the van der Waals cathode, which allows silver ion intercalation/de-intercalation, creating a high diffusion barrier to modulate ion motion. The strategy can achieve analogue resistive switching with an on/off ratio up to 10<sup>8</sup>, over 8-bit conductance states and attojoule-level power consumption. We use the analogue properties to perform the chip-level simulation of a convolutional neural network that offers high recognition accuracy.</p>","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"107 1","pages":""},"PeriodicalIF":34.3,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142451826","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, measuring biomarkers, such as heart rate and respiration, without physical contact remains a challenge in these environments due to issues related to movement and external interference. Here we report a metamaterial biosensor that can capture cardiopulmonary signals in kinetic environments without being in contact with the body. Fabricated using digital embroidery, the biosensor can be integrated with a safety harness and can detect physiological motion through near-field interactions between wireless signals and the body. We show that the approach is capable of continuous, hour-long recording of heartbeat and respiration in an airline cabin simulator. We also show that the biosensor can operate in a moving car, and exhibits no degradation in accuracy compared with a stationary environment. A textile metamaterial sensor can wirelessly measure biomarkers—such as heart rate and respiration—in vehicles and shows no accuracy degradation when operating in moving environments.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"7 11","pages":"1025-1034"},"PeriodicalIF":33.7,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142440829","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}

Fuzzy logic systems can potentially provide more efficient edge implementations due to their compactness and capacity to manage uncertain data. However, their hardware realization remains difficult, primarily because implementing reconfigurable membership function generators using conventional technologies requires high circuit complexity and power consumption. Here we report a multigate van der Waals interfacial junction transistor based on a molybdenum disulfide/graphene heterostructure that can generate tunable Gaussian-like and π-shaped membership functions. By integrating these generators with peripheral circuits, we create a reconfigurable fuzzy controller hardware capable of nonlinear system control. This fuzzy logic system can also be integrated with a few-layer convolution neural network to form a fuzzy neural network with enhanced performance in image segmentation. An interfacial junction transistor based on a molybdenum disulfide/graphene heterostructure can generate tunable π-shaped and Gaussian-like membership functions, allowing membership function generators for fuzzy logic systems to be implemented with low device count and energy cost.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"7 10","pages":"876-884"},"PeriodicalIF":33.7,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142436281","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}

M3D integration can also provide transistor-level partitioning and material heterogeneity. However, there are few large-area demonstrations of M3D integration using non-silicon materials. Here, we report heterogeneous M3D integration of two-dimensional materials using a dense inter-via structure with an interconnect (I/O) density of 62,500 I/O per mm2. Our M3D stack consists of graphene-based chemisensors in tier 2 and molybdenum disulfide (MoS2) memtransistor-based programmable circuits in tier 1, with more than 500 devices in each tier. Our process allows the physical proximity between sensors and computing elements to be reduced to 50 nm, providing reduced latency in near-sensor computing applications. Our manufacturing process also stays below 200 °C and is thus compatible with back-end-of-line integration. Tiers containing graphene-based sensors and molybdenum disulfide-based processors can be vertically stacked using a monolithic integration process, with an interconnect density of 62,500 per mm2.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"7 10","pages":"892-903"},"PeriodicalIF":33.7,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142385118","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}
