Emerging materials and architectures offer promising pathways for further miniaturization. Bismuth oxyselenide (Bi2O2Se), an air-stable 2D semiconductor, exhibits high mobility, a suitable bandgap and a native high-κ oxide (Bi2SeO5), resembling silicon and its SiO2 counterpart. These properties suggest compatibility with industrial processes, positioning Bi2O2Se for next-generation high-performance computing. This Review summarizes recent advances in material synthesis, wafer-scale integration and device architectures, highlighting key challenges in the lab-to-fab transition. Finally, a roadmap is proposed to guide future innovations in ultra-scaled, energy-efficient electronics.

Pain management in humans is an unresolved problem with substantial medical, societal and economic implications. Traditional strategies such as opioid-based medications are highly effective but pose many long-term risks, including addiction and overdose. In this Review, we discuss these persistent challenges in medical care along with advances in bioelectronics that enable safer and more effective alternative treatments. Emerging approaches leverage wireless embedded networks and machine learning to accurately detect and quantify the symptoms of pain, establishing a foundation for targeted, on-demand treatment. These platforms offer a powerful complement to wearable and implantable neural interfaces that can control these symptoms with unprecedented spatiotemporal and functional selectivity. Now, emotional and cognitive aspects of pain can be addressed through immersive multisensory engagement with systems for augmented and virtual reality. Trends in diagnostic and interventional technologies show how their integration is well suited to addressing some of the most intractable problems in pain management. Pain is a profound and unresolved health challenge, and current interventions are not sufficient for safe and effective pain management. Bioelectronics presents solutions for monitoring the symptoms of pain and treating these symptoms in a targeted manner.
人类疼痛管理是一个尚未解决的问题,具有重大的医学、社会和经济意义。阿片类药物等传统策略非常有效,但存在许多长期风险,包括成瘾和过量服用。在这篇综述中,我们讨论了医疗保健中这些持续存在的挑战,以及生物电子学的进步,使更安全、更有效的替代治疗成为可能。新兴方法利用无线嵌入式网络和机器学习来准确检测和量化疼痛症状,为有针对性的按需治疗奠定基础。这些平台为可穿戴和植入式神经接口提供了强大的补充,可以以前所未有的时空和功能选择性控制这些症状。现在,疼痛的情感和认知方面可以通过与增强现实和虚拟现实系统的沉浸式多感官参与来解决。诊断和介入技术的发展趋势表明,它们的结合非常适合解决疼痛管理中一些最棘手的问题。疼痛是一个深刻而未解决的健康挑战,目前的干预措施不足以实现安全有效的疼痛管理。生物电子学为监测疼痛症状和有针对性地治疗这些症状提供了解决方案。

High-fidelity wearable bioelectronics aims to establish seamless integration between electronic devices and biological systems to enable real-time health monitoring, disease diagnosis, and multimodal interaction. Central to this integration are the bio–electronic interfaces, which require conformal alignment and optimized electrical and mechanical properties to ensure stable and accurate signal acquisition. Traditional bioelectronic devices frequently fail to achieve good conformity at the microscale and nanoscale, lacking fabrication processes feasible for customized three-dimensional (3D) microstructures and nanostructures. In this Review, we discuss advances in 3D manufacturing technologies, focusing on those techniques that, enabling the fabrication of cross-scale, multimaterial structures, address key challenges in spatial complexity and mechanical mismatch at the bio–electronic interface. These innovations promote both long-term wearability and high-fidelity signal integrity. Interdisciplinary collaboration — particularly the integration of artificial intelligence — is essential for driving successful transformation in the field. Delivering cost-effective and scalable solutions for the fabrication of high-fidelity bioelectronic devices is crucial to realize their transformative potential in healthcare, human–machine interaction, and personalized medicine. Wearable bioelectronics integrates functional electronic devices with biological systems to enable real-time health monitoring and disease diagnosis. This Review explores advancements in three-dimensional manufacturing technologies for high-fidelity biosensors, addressing challenges related to fabrication, signal integrity, and long-term wearability.
高保真可穿戴生物电子学旨在建立电子设备与生物系统之间的无缝集成,实现实时健康监测、疾病诊断和多模态交互。这种集成的核心是生物电子接口,它需要共形对准和优化的电气和机械性能,以确保稳定和准确的信号采集。传统的生物电子器件往往不能在微尺度和纳米尺度上达到良好的一致性,缺乏可定制的三维(3D)微结构和纳米结构的制造工艺。在这篇综述中,我们讨论了3D制造技术的进展,重点是那些能够制造跨尺度、多材料结构的技术,解决了生物电子界面空间复杂性和机械不匹配的关键挑战。这些创新提高了长期可穿戴性和高保真信号完整性。跨学科合作——尤其是人工智能的整合——对于推动该领域的成功转型至关重要。为制造高保真生物电子器件提供经济高效且可扩展的解决方案,对于实现其在医疗保健、人机交互和个性化医疗领域的变革潜力至关重要。可穿戴生物电子学将功能电子设备与生物系统集成在一起,实现实时健康监测和疾病诊断。本综述探讨了高保真生物传感器三维制造技术的进展,解决了与制造、信号完整性和长期可穿戴性相关的挑战。

Digital information has permeated all aspects of life, and diverse forms of information exert a profound influence on social interactions and cognitive perceptions. In contrast to the flourishing of digital interaction devices for sighted users, the needs of blind and partially sighted users for digital interaction devices have not been adequately addressed. Current assistive devices often cause frustration in blind and partially sighted users owing to the limited efficiency and reliability of information delivery and the high cognitive load associated with their use. The expected rise in the prevalence of blindness and visual impairment due to global population ageing drives an urgent need for assistive devices that can deliver information effectively and non-visually, and thereby overcome the challenges faced by this community. This Perspective presents three potential directions in assistive device design: multisensory learning and integration; gestural interaction control; and the synchronization of tactile feedback with large-scale visual language models. Future trends in assistive devices for use by blind and partially sighted people are also explored, focusing on metrics for text delivery efficiency and the enhancement of image content delivery. Such devices promise to greatly enrich the lives of blind and partially sighted individuals in the digital age. Blind and partially sighted individuals face considerable challenges when interacting with digital information. This Perspective highlights important bottlenecks in information accessibility, design considerations for future wearable assistive devices and the outlook for improved access to and delivery of information in text and images.
数字信息已经渗透到生活的方方面面,各种形式的信息对社会交往和认知观念产生了深刻的影响。与为视力正常的用户提供的数字交互设备的蓬勃发展相比,盲人和弱视用户对数字交互设备的需求没有得到充分的解决。由于信息传递的效率和可靠性有限,以及与使用相关的高认知负荷,目前的辅助装置经常使盲人和弱视用户感到沮丧。由于全球人口老龄化,失明和视力障碍的患病率预计会上升,这促使人们迫切需要能够有效地和非视觉地传递信息的辅助装置,从而克服这个社区面临的挑战。这一观点提出了辅助装置设计的三个潜在方向:多感官学习和整合;手势交互控制;触觉反馈与大尺度视觉语言模型的同步。还探讨了盲人和弱视人群使用的辅助设备的未来趋势,重点是文本传递效率的指标和图像内容传递的增强。这些设备有望极大地丰富数字时代盲人和弱视人士的生活。盲人和弱视人士在与数字信息互动时面临相当大的挑战。本展望强调了信息可及性的重要瓶颈,未来可穿戴辅助设备的设计考虑因素,以及改进文本和图像信息的获取和传递的前景。

The rapid development of generative artificial intelligence and large models, including large vision models (LVMs), has accelerated their wide applications in medicine. Robot-assisted surgery (RAS) or surgical robotics, in which vision has a vital role, typically combines medical images for diagnostic or navigation abilities with robots with precise operative capabilities. In this context, LVMs could serve as a revolutionary paradigm towards surgical autonomy, accomplishing surgical representations with high fidelity and physical intelligence and enabling high-quality data use and long-term learning. In this Perspective, vision-related tasks in RAS are divided into fundamental upstream tasks and advanced downstream counterparts, elucidating their shared technical foundations with state-of-the-art research that could catalyse a paradigm shift in surgical robotics research for the next decade. LVMs have already been extensively explored to tackle upstream tasks in RAS, exhibiting promising performances. Developing vision foundation models for downstream RAS tasks, which is based on upstream counterparts but necessitates further investigations, will directly enhance surgical autonomy. Here, we outline research trends that could accelerate this paradigm shift and highlight major challenges that could impede progress in the way to the ultimate transformation from ‘surgical robots’ to ‘robotic surgeons’. Robot-assisted surgery relies heavily on vision and generally integrates medical imaging for diagnostic and/or navigation purposes with robots that offer accurate surgical functions. This Perspective discusses how large vision models can enhance vision-related tasks in robot-assisted surgery transforming ‘surgical robots’ into ‘robotic surgeons’.
生成式人工智能和大模型(包括大视觉模型)的快速发展,加速了其在医学上的广泛应用。机器人辅助手术(RAS)或外科机器人,其中视觉具有至关重要的作用,通常将用于诊断或导航能力的医学图像与具有精确手术能力的机器人相结合。在这种情况下,lvm可以作为手术自主性的革命性范例,以高保真度和物理智能完成手术表征,并实现高质量的数据使用和长期学习。从这个角度来看,RAS中与视觉相关的任务被分为基本的上游任务和高级的下游任务,阐明了它们与最先进的研究共同的技术基础,这些研究可以催化下一个十年手术机器人研究的范式转变。lvm已经被广泛地用于解决RAS中的上游任务,并表现出良好的性能。开发下游RAS任务的视觉基础模型将直接提高手术自主性,该模型基于上游任务,但需要进一步研究。在这里,我们概述了可能加速这种范式转变的研究趋势,并强调了可能阻碍从“手术机器人”到“机器人外科医生”最终转变的主要挑战。机器人辅助手术在很大程度上依赖于视觉,通常将用于诊断和/或导航目的的医学成像与提供精确手术功能的机器人集成在一起。本展望讨论了大视觉模型如何在机器人辅助手术中增强视觉相关任务,将“手术机器人”转变为“机器人外科医生”。
