Advances in information technology have enabled ubiquitous health monitoring at home, which is particularly useful for patients, who have to live alone. We have focused on the automatic and unobtrusive measurement of biomedical signals and activities of patients. We have constructed wireless communication networks in order to transfer data. The networks consist of Bluetooth and Wireless Local A...

serious concerns have been expressed about potential health risks of nano silver containing consumer products (agnps) therefore regulatory health risk assessment on such nanoparticles has become mandatory for the safe use of agnpsinbiomedicalproducts with special concerns to the mutagenic potentials. in this study, we examined the inhibitory and mutagenicity effects of agnps in three different ...

Accurate sensing of ion concentrations in body fluids is importance to monitor cell functions, and any deviation the concentration serves as a warning sign pathophysiological conditions. Here, fabrication approach for an integrated device consisting two electrochemical transistors, capable selective simultaneous detection between potassium sodium ions analyte demonstrated. A common in-plane gat...

Nanosecond plasmas in liquids are being used for water treatment, electrolysis or biomedical applications. The exact nature of these very dynamic and most important their ignition physics strongly debated. itself may be explained by two competing hypothesis: (i) via field effects (ii) electron multiplication nanovoids. Both hypothesis supported theory, but experimental data sparse due to the di...

A comfortable health monitoring system named WEALTHY is presented. The system is based on a wearable interface implemented by integrating fabric sensors, advanced signal processing techniques and modern telecommunication systems, on a textile platform. Conducting and piezoresistive materials in form of fibre and yarn are integrated in a garment and used as sensors, connectors and electrode elem...

The cooperation between neuroscience and biomedical engineering gave rise to a recent, but growing research field, known as neuroengineering. We follow its principles to have a system providing basic descriptions of the visual world to the brain’s cortex. We describe a set of software and hardware tools to interface with neural tissue, in order to transmit visual information encoded into a bioi...

A simple thermodynamic theory of the equilibrium potentials of membrane electrodes is formulated and applied to the glass electrode for measurement of pH. The new formulation assumes the selective adsorption or binding of specific ions on the surface of the membrane which may or may not be permeable to the ion, and includes the conventional derivation based on reversible ion transport across me...

Recently, non-invasive techniques to measure the fetal electrocardiogram (FECG) signal have given very promising results. However, the important question of the number and the location of the external sensors has been often discarded. In this paper, an electrode-array approach is proposed; it is combined with a sensor selection algorithm using a mutual information criterion. The sensor selectio...

Microneedles are expected to have greater demand in biomedical applications like sensing, electroporation & drug delivery in the future and there is need for development of fabrication process which is simple, economical and productive. Present work discusses about fabrication of PDMS (polydimethylsiloxane) micro needle array electrode for bio-potential signal measurement like EEG by micromachi...
