Abstract

The recent development of numerous smart wearable electronics has accelerated progress in human–machine interaction and health monitoring technologies. However, processing the abundant motion and physiological signals collected by wearable devices on conventional off-site digital computers often results in significant latency and high energy consumption. Here, we introduce a flexible, multisynapse electrolyte-gated oxide transistor (EGOT) based on an indium tin oxide channel for advanced wearable health monitoring. By integrating synaptic functionalities, the EGOT effectively processes electrocardiogram (ECG) and respiration signals. This unprecedented modulation precision in conductance states, enabled by the dual-gate architecture, achieves high-efficiency signal integration effects. The device adapts to input pulses of varying frequency, amplitude, and duration, enabling sophisticated signal differentiation and dynamic health evaluation. The flexible EGOT device, with integrated ECG and breathing on-demand signal analysis, has achieved over 90% accuracy in physiological signal classification. This device holds vast promise for neuromorphic hardware and functional integration, bridging intelligent diagnostics in healthcare applications.

用于集成生理信号识别的柔性双门控突触晶体管

近年来，许多智能可穿戴电子产品的发展加速了人机交互和健康监测技术的进步。然而，在传统的非现场数字计算机上处理可穿戴设备收集的大量运动和生理信号往往会导致显著的延迟和高能耗。在这里，我们介绍了一种灵活的，基于氧化铟锡通道的多突触电解质门控氧化物晶体管（EGOT），用于先进的可穿戴健康监测。通过整合突触功能，EGOT有效地处理心电图（ECG）和呼吸信号。这种前所未有的电导状态调制精度，由双栅极架构实现，实现高效率的信号集成效果。该设备适应不同频率、幅度和持续时间的输入脉冲，实现复杂的信号分化和动态健康评估。灵活的EGOT设备，集成了ECG和呼吸按需信号分析，生理信号分类准确率达到90%以上。该设备为神经形态硬件和功能集成提供了广阔的前景，在医疗保健应用中架起了智能诊断的桥梁。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
