Electrical characterization of in-house fabricated polysilicon micro-gap for yeast concentration measurement

Fabrication and electrical characterization of micro-gaps and their properties are discussed with their applications in electrochemical sensors and bimolecular detection. To understand the relationship between the biosensor and micro-structure we have carried out the fabrication and characterization of micro-gap structures for yeast concentration measurement. In this paper two photo mask designs are used. The first mask...

Effect of geopathic stress zone on human body voltage and skin resistance

Geopathic stress zones are places on the surface of the Earth known to cause health problem. Empirical knowledge of the existence of geopathic stress is probably as old as mankind. The aim of this study is to evaluate the effect of geopathic stress on human body. It further tries to scientifically evaluate dowsing phenomenon by measuring body voltage, skin resistance, using V-20 bio voltmeter, GSR-2 biofeedback...

Atomic force microscopy (AFM) and X-ray diffraction (XRD) studies of BiFeO3 nanoparticles with sol–gel

Recently, there has been considerable interest in studying nanostructural properties of Bismuth (Bi) as a good electrode of electro-analysis, shape–memory alloys and photo-typical multiferric devices. We have thus demonstrated a series of experiments to synthesis Bi and BiFeO3 (BFO) nanoparticles using sol–gel method at ambient pressure and study their nanostructural properties using tapping mode of...

Smart crack detection of a cracked cantilever beam using fuzzy logic technology with hybrid membership functions

  Damage detection methods have been considerably increased over the past few decades. A crack in a structural member introduces local flexibility that would affect vibration response of the structure. This property may be used to detect existence of a crack together with its location and depth in the structural member. The presence of damage leads to changes in some of the lower natural frequencies and mode...
