We demonstrate THz metamaterials as efficient label-free detectors for microorganisms such as fungi, bacteria, and viruses. A shift in the resonant frequency is observed following the deposition of various living and viable microorganisms, which arises due to the change in the effective dielectric constant in a capacitive gap of the metamaterials. The metamaterial sensing is a universal method, while...
Temperature knowledge may be beneficial to improve the outcomes of thermal treatments for tumor ablation. Among several thermometric methods, contactless approaches based on diagnostic imaging techniques are attractive for this field. Computed Tomography (CT) images are sensitive to temperature, so some groups of research are working to assess the feasibility of CT-based thermometry for monitoring...
In order to perform fall risk assessments using wearable inertial sensors in older adults in their natural settings where falls are likely to occur, a first step is to automatically segment and classify sensor signals of human movements into the known ‘activities of interest’. Sensor data from such activities can later be used through quantitative and qualitative analysis for differentiating fallers...
Falls are a major cause of death and morbidity in older adults. In recent years many researchers have examined the role of wearable inertial sensors (accelerometers and/or gyroscopes) to automatically detect falls. The primary goal of such fall monitors is to alert care providers of the fall event, who can then commence earlier treatment. Although such fall detection systems may reduce time until...
This paper presents a new DVS sensor with one order of magnitude improved contrast sensitivity over previous reported DVSs. This sensor has been applied to a bio-inspired event-based binocular system that performs 3D event-driven reconstruction of a scene. Events from two DVS sensors are matched by using precise timing information of their ocurrence. To improve matching reliability, satisfaction of...
Introduction: Plasmodium vivax malaria is one of the most important infectious diseases plaguing humanity and causes significant mortality and morbidity worldwide. The gold standard of P. vivax malaria diagnosis is the microscopy of blood smears. Although microscopy is a rapid, cost‐effective, and readily applicable method, it has many disadvantages, including low sensitivity, specificity, and precision...
Nanoscale electronic devices have the potential to achieve exquisite sensitivity as sensors for the direct detection of molecular interactions, thereby decreasing diagnostics costs and enabling previously impossible sensing in disparate field environments. Semiconducting nanowire-field effect transistors (NW-FETs) hold particular promise, though contemporary NW approaches are inadequate for realistic...
Understanding how the mechanoreceptor neurons of Caenorhabditis elegans mediate mechanotransduction can unravel how touch works, but new tools are required to quantitatively analyze the relationship between mechanical loading and the physiological response. Here we present a piezoresistive cantilever-based force clamp system that can apply user-defined force profiles to C. elegans. We present a novel...
