Silver nanoparticles are valuable in the field of plasmonics since silver has a higher field enhancement factor compared to other metals that possess plasmonic properties. The plasmonic properties of silver nanoparticles can be finely tuned to the incident light wavelength through their size, shape and dielectric environment, and they have long-term stability. In this work, an ultrathin polymer ...

This work aims to investigate the behaviour of a simple interdigital sensor structure for glucose monitoring in response to distortions in the skin-topology and differences in skin undulation during use. The study then extends to consider a flexible sensor structure which is better able to contour to the skin variations. The simulation work shows that skin distortions and undulation ...

High Intensity Focused Ultrasound (HIFU) is used as a noninvasive technique of tissue heating and ablation for different medical treatments. This paper presents a quantitative comparison of HIFU acoustic fields experimentally obtained versus simulated acoustic fields. Acoustic field characterization was realized in two HIFU transducers using water as a propagation medium. Also, simulations were ...

An implementation of the Electrical Impedance Tomography (EIT) forward problem in a generalist FEM package is presented. It fulfils the complete electrode model boundary conditions, combining current injection with contact impedance on a single boundary. Our implementation is benchmarked with the EIDORS FEM library. The Comsol Multiphysics environment proves consistent and provides a flexible ...

This work describes the design and optimization of three prototypes of microelectromechanical systems (MEMS) capacitive accelerometer-based middle ear microphone. The microphone is intended for middle ear hearing aids as well as future fully implantable cochlear prosthesis. The analysis is done using COMSOL Multiphysics®. The maximum applied acceleration was considered 1g. Human temporal bones ...

This article describes the design of MEMS based cantilever structure intended for determination of blood group and it is compared with manual method. Cantilever structure design has a sensing layer and when a blood sample comes in contact with this, results in coagulation. The surface tension in turn occurs due to chemical and biological reactions of antigen and antibodies resulting in ...

In 1901 Weiss proposed an equation predicting activation of nerve fibers by electrical stimulation, used in neuroscience and neuromodulation, which applies electric fields to modify nerve behavior in neurological disorders. Weiss’ equation is relative to geometry, electrode array, tissue conductivities, and waveform since it uses electrode amplitude. We replicated a leading calibrated nerve ...

When an electronic device is worn for extended periods, possibly in direct contact with human skin, heat must be safely transferred away from the device, without exceeding standards and regulatory temperature limits on the skin and on the exposed surfaces of the device. Heat transfer is dominated by convective heat transfer to the surrounding air (possibly trapped air under clothing), and by ...
