However, scaling up analogue computing platforms by simply increasing the number of devices leads to challenges such as device-to-device variation. Here we report scalable analogue computing and neural networks in the synthetic frequency domain using an integrated nonlinear phononic platform on lithium niobate. This synthetic-domain computing is robust to device variations, as vectors and matrices are concurrently encoded at different frequencies within a single device, achieving a high throughput per area. Leveraging inherent nonlinearities, our device-aware neural network can perform a four-class classification task with an accuracy of 98.2%. The nonlinear phononic computing hardware also maintains consistent performance over a wide operational temperature range (characterized up to 192 °C). Our synthetic-domain computing combines single-device parallelism, inherent nonlinearity and environmental stability, and could be of use in edge computing applications in which power efficiency and environmental resilience are crucial.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"103 1","pages":""},"PeriodicalIF":34.3,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144900905","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}

Stochastic magnetic tunnel junctions are potential entropy sources for such Ising machines. However, scaling up stochastic magnetic tunnel junction probabilistic Ising machines requires the fine control of a small magnetic energy barrier and duplication of area-intensive digital-to-analogue converter elements across large numbers of devices. The non-spintronic components of these machines are also typically created using general-purpose processors or field-programmable gate arrays. Here we report a probabilistic computer that is based on an application-specific integrated circuit fabricated using 130-nm foundry complementary metal–oxide–semiconductor technology and uses voltage-controlled magnetic tunnel junctions as its entropy source. With the system, we implement integer factorization as a representative hard optimization problem using probabilistic Ising-machine-based invertible logic gates created with 1,143 probabilistic bits. The application-specific integrated circuit uses stochastic bit sequences read from an adjacent voltage-controlled magnetic tunnel junction chip. The magnetic tunnel junctions are thermally stable in the absence of a voltage and synchronously generate random bits without the use of digital-to-analogue converter elements using the voltage-controlled magnetic anisotropy effect.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"20 1","pages":""},"PeriodicalIF":34.3,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144824878","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}

As a result, it is possible to create an instrument capable of realizing all three primary electrical units, but the development of such a system remains challenging. Here we report a unified realization of the volt, ohm and ampere by integrating a quantum anomalous Hall resistor (QAHR) and a programmable Josephson voltage standard (PJVS) in a single cryostat. Our system has a quantum voltage output that ranges from 0.24 mV to 6.5 mV with combined relative uncertainties down to 3 μV V−1. The QAHR provides a realization of the ohm at zero magnetic field with uncertainties near 1 μΩ Ω−1. We use the QAHR to convert a longitudinal current to a quantized Hall voltage and then directly compare that against the PJVS to realize the ampere. We determine currents in the range of 9.33–252 nA, and our lowest uncertainty is 4.3 μA A−1 at 83.9 nA. For other current values, a systematic error that ranges from −10 μA A−1 to −30 μA A−1 is present due to the imperfect isolation of the PJVS microwave bias.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"1 1","pages":""},"PeriodicalIF":34.3,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144819353","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, typical probes for recording neural activity in the brain are limited to two-dimensional interfacing due to the planar semiconductor fabrication process. Here we report a rolling-of-soft-electronics approach to create monolithic three-dimensional (3D) neural probes with high scalability and design flexibility. Compared with previous stacking or assembly methods, the approach directly transforms a planar device into a 3D probe by leveraging the softness of flexible electrodes. The electrode shanks are initially fabricated in a single plane and then connected to a flexible spacer. By varying the features of planar design, such as shank pitch and spacer layer thickness, the device can then be deterministically rolled into versatile 3D probe designs containing hundreds of electrodes. With the system, we demonstrate single-unit spike recording in vivo in rodent and non-human primate models. We also show that the probe can provide microscopy-like 3D spatiotemporal mapping of spike activities in the rodent visual cortex, with five-week-long recording stability and promising 3D decoding performance of visual orientation.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"41 1","pages":""},"PeriodicalIF":34.3,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144812936","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}

Hardware that incorporates synaptic plasticity—adaptive changes that strengthen or weaken synaptic connections—has been explored, but mimicking the full spectrum of learning and memory processes requires the interplay of multiple plasticity mechanisms including intrinsic plasticity. Here we show that an integrate-and-fire neuron can be created by combining a dynamic random-access memory and an inverter that are based on wafer-scale monolayer molybdenum disulfide films. In the system, the voltage in the dynamic random-access memory capacitor—that is, the neuronal membrane potential—can be modulated to emulate intrinsic plasticity. The module can also emulate the photopic and scotopic adaptation of the human visual system by dynamically adjusting its light sensitivity. We fabricate a 3 × 3 photoreceptor neuron array and demonstrate light coding and visual adaptation. We also use the neuron module to simulate a bioinspired neural network model for image recognition.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"33 1","pages":""},"PeriodicalIF":34.3,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144812938","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}
