We introduce a novel integration of vision sensors in the form of a dual sensor system. The dual sensor system combines three distinct units: an optical localizer and two RGB-D sensors. This system is uniquely capable of concurrently providing real-time 3D shape information for deformable objects and accurate pose tracking data for medical instruments. This capability positions the dual sensor with immense potential for application in image-guided surgical navigation, robotic systems, and robot-assisted automation for surgical procedures involving deformable target objects. This paper provides an overview of the design, fabrication and a one-time calibration methodology of the dual sensor. An experiment was performed to assess the calibration accuracy of the dual sensor. Experimental results indicated that the dual sensor system delivers a level of accuracy that renders it suitable for deployment within the envisioned scope of applications.Clinical relevance- The presented dual sensor provides real-time shape scanning of intra-operatively deforming objects and instrument tracking capabilities simultaneously, contributing to successful outcomes of diverse computer-integrated surgeries dealing with non-rigid surgical targets such as breast, face, and incised skin area.

A bifunctional tubular step-scheme CoS/CdS heterostructure was successfully synthesized for efficient photoelectrochemical (PEC) detection coupled with the degradation of tetracycline (TC). It was found that so-obtained heterostructure could effectively suppress the recombination of photo-generated carriers and display larger PEC responses owing to the internal electrostatic field. Upon adding TC, the photocurrent signal of CoS/CdS heterostructure was specifically activated due to the direct consumption of holes in CdS component by TC, resulting in significantly enhanced charge separation.

Sweat, as a metabolic byproduct, encompasses a diverse array of molecular information pertinent to our physiological states and overall health. The extraction of minute quantities of sweat, coupled with sensitive monitoring and identification of its internal molecular components, constitutes an effective strategy for assessing bodily conditions. We engineer a Janus membrane utilizing electrospinning techniques for application on human skin to facilitate sweat collection.

Objective: Due to the growing demand for personal health monitoring in extreme environments, continuous monitoring of core temperature has become increasingly important. Traditional monitoring methods, such as mercury thermometers and infrared thermometers, may have limitations in tracking real-time fluctuations in core temperature, especially in special application scenarios such as firefighting, military, and aerospace. This study aims to develop a non-invasive, continuous core temperature prediction model based on machine learning, addressing the limitations of traditional methods in extreme environments.

Seed viability, a key indicator for quality assessment, directly impacts the emergence of field seedlings. The existing nondestructive testing model for maize seed vitality based on naturally aged seeds and predominantly relying on single-modal data like MV and RS, achieves an accuracy of less than 70 %. To elucidate the influence of different data on model accuracy, this study proposes the MSCNSVN model for detecting seed viability by collecting multisensor information from maize seeds using sensors, such as MV, RS, TS, FS, and SS.

Developing analytical methods for simultaneous detection of multiple antibiotic residues is crucial for environmental protection and human health. In this study, a dual lanthanide fluorescence probe (GDP-Eu-Tb) based on nucleotides has been designed. The addition of quinolone antibiotics (QNs) quench the Eu fluorescence signal through the inner filter effect (IFE) and exhibit characteristic peaks, enabling ratio fluorescence detection of levofloxacin (LVLX), gatifloxacin (GTLX), and moxifloxacin (MXLX).
