Plasmonic properties of Au-Ag nanoparticles: Distinctiveness of metal arrangements by optical study

The core-shell arrangement of binary compound plasmonic nanoparticles (NPs) is usually verified by plasmonic extinction spectra, since microscopy-based methods cannot provide analysis of many NPs. Here, we discuss possible scenarios of different metal arrangements: (i) core-shell model, (ii) bimetallic model, and (iii) mixture of pure metal NPs. The possibility of distinguishing individual cases is discussed in accordance with numerical simulations and an alternative characterization is suggested.

Wearable healthcare electronics for 24-7 monitoring with focus on user comfort

Human health is important for people in any age. Healthcare addresses a market of more than 10% of the European gross domestic product. An ageing population will have an enormous impact on society and the economy. The objective of this article is to provide a view of some latest research innovations in field of bioelectronics. Among these a short description of non-invasive hydration sensor, glucose sensor, hemodynamic sensor preparation and implementation methods is provided followed by a proposal of a design of flexible plaster for ECG monitoring in function of a heart holter. A design of remote sensing units requires consideration of several functional blocs with following integration and evaluation phase. For the integration of such system several functional blocks are needed for the preparation of medical smart system cluster, such as energy source or harvester with supercaps or battery, communication (integrated antennas), new organic materials or biocompatible housing. Preparation of such system is deeper described by the example of an ECG plaster holter.

Electrode configuration for EMG measurements

This paper explains problematic of EMG (electromyography) signal measurements. Described experiments are partition of complex project “MEDISYS” dedicated to design of modern medical equipment, consisting the latest technologies and IC. The design is based on low noise wireless measurement block (for ECG, EMG and EEG monitoring) followed by actuator block with mechanical constructions and control electronic.

Application of Acceleration Sensors in Physiological Experiments

Abstract This paper illustrates a promising application of an accelerometer sensor in physiological research, we demonstrated use of accelerometers for monitoring the standard proband physical activity (PA) and also in special applications like respiration and mechanical heart activity, the so-called seismocardiography (SCG) monitoring, physiological activation monitoring and mechanomyography (MMG)
