A Full‐Range Proximity‐Tactile Sensor Based on Multimodal Perception Fusion for Minimally Invasive Surgical Robots

Advanced Science, EarlyView.
A full‐range proximity‐tactile sensing module is developed for safe operation of surgical robots, which performs multimodal fusion perception through ultrasonic sensor for long‐range proximity detection, capacitive sensor for close‐range proximity sensing, and triboelectric sensor for tactile sensing.

Probing the Challenge of P‐Type Semiconductors in Long‐Chain VOC Detection: 3D Micro‐Flower Zinc Cobaltate Heterojunction Sensors

Advanced Science, EarlyView.
Fe@WO3/ZnCo2O4 n‐p heterojunction sensor exhibits excellent room‐temperature sensing toward tetradecane, with a low detection limit of 78.4 ppb and short recovery time. The good performance is attributed to synergistic effects from heterojunctions, heteroatom doping, oxygen vacancies, high‐energy facets, and theoretical validations.

Wearable Bioelectronics for Home‐Based Monitoring and Treatment of Muscle Atrophy

Advanced Science, EarlyView.
As an inevitable disease, muscle atrophy has received more attention. Because the factors that induce this disease are diverse, achieving a complete cure is still impossible. Wearable bioelectronics provides a more comfortable, low‐cost, and efficient way of home care for the monitoring and treatment of muscle atrophy. Therefore, this review summarizes

Accelerating Sono‐Piezoelectric Charge Transport for Antibacterial Therapy and Bone Regeneration by Metal‐Deficient TiO2 Spin‐Polarization Effect

Advanced Science, EarlyView.
The deficient TiO2 (DTO) and Barium titanate (BTO) heterojunction treats osteomyelitis through SDT. The spin‐polarization effect induced by the unpaired spin electrons in Ti atoms can expedite the transfer of ultrasonic piezoelectric charges in BTO, enhancing surface sonocatalytic efficiency.

Ultrasound‐Mediated Biotransfection of Engineered Bone Marrow Mesenchymal Stem Cells in Treated Bone Defects through Intracellular Cavitation

Advanced Science, EarlyView.
Ultrasound‐mediated biotransfection through intracellular cavitation increases plasmid nuclear translocation and gene transfection efficiency by 284.7% and 131.6% in engineered bone marrow mesenchymal stem cells (BMSCs) compared to traditional ultrasound‐targeted microbubble destruction techniques. The maintained bone morphogenetic protein 2 expression
