Abstract Federated learning (FL) is an attractive distributed machine learning paradigm that enables numerous clients to collaboratively train a model under the coordination of a central server, while keeping the training data private. However, without sufficient incentive, clients may be reluctant to participate in FL due to the associated training costs and variant availability. Moreover, […]

Abstract Organic electrochemical transistors (OECT) have emerged as a promising technology paradigm for wearable healthcare applications. However, several major challenges limit their widespread adoption in real-world applications: 1) the lack of conformable and stretchable OECT units to reduce the mechanical mismatch between devices and the soft human body; 2) the lack of reliable fabrication methods […]

Abstract Continuous glucose monitoring systems (CGMs) are critical toward closed-loop diabetes management. The field’s progress urges next-generation CGMs with enhanced antinoise ability, reliability, and wearability. Here, we propose a coin-sized, fully integrated, and wearable CGM, achieved by holistically synergizing state-of-the-art interdisciplinary technologies of biosensors, minimally invasive tools, and hydrogels. The proposed CGM consists of three […]

Abstract Organic electrochemical transistors (OECTs) are emerging as next-generation biosensing technologies due to their capacity to amplify biosignals at low power, making them particularly suitable for developing sensitive wearable sensors capable of detecting low-concentration biosignals. Current technologies predominantly focus on maximizing the transconductance (amplification capability) of OECTs, which proves effective for direct electrophysiological detection. However, […]

Abstract Chronic wounds resulting from underlying diseases like diabetes pose a significant healthcare challenge, necessitating continuous monitoring and timely intervention to avoid medical complications. Smart bandages integrating multifunctional sensors offer the potential for monitoring chronic wounds caused by diabetes and other underlying diseases, thereby relieving hospitals from labor-intensive analysis and avoiding medical delays. We fabricated […]

Abstract The emergence of the metaverse and digital twin technologies necessitates addressing key challenges in mapping the large-scale physical world to virtual domains. Integrated sensing and communication techniques, particularly wireless communications and radar sensing in millimetre-wave bands, will play a crucial role in achieving this goal and will be a significant enabling technology for 6G […]

Abstract Ultrasound, in conjunction with microbubbles, offers a promising drug delivery method. This approach, known as sonoporation, enables targeted drug delivery by temporarily permeating biological barriers (e.g., cell membrane, vessel wall) under ultrasound insonation. It shows potential for a wide range of therapeutic agents, including chemotherapeutics, nucleic acids, peptides, and antibodies. While preclinical studies have […]
