Moisture content is an important factor in corn breeding and cultivation. A corn breed with low moisture at harvest is beneficial for mechanical operations, reduces drying and storage costs after harvesting and, thus, reduces energy consumption. Nondestructive measurement of kernel moisture in an intact corn ear allows us to select corn varieties with seeds that have high dehydration speeds in ...

In the previous chapter we have described an experimental technique which allows us to measure the local temperature of the sample under the application of a strong electric field.. We have also described setups for electrical impedance measurement and optical studies. In this chapter we present experimental results obtained using these techniques to study the electric field effect on the nemat...

The electric impedance of cultured myoblasts oriented on the scaffold with micro pattern has been measured between surface electrodes in vitro. Several parallel lines of micro rectangular ridges (0.001 mm height, 0.003 mm width, and 0.003 mm interval) have been made between a pair of the surface titanium electrodes at the surface of the scaffold of glass by the photolithography technique. C2C12...

This paper provides a very brief overview of the capabilities and recent accomplishments of many of the low frequency electrical metrology projects at the National Institute of Standards and Technology. The projects presented here include the 5 main electrical measurement services projects (dc voltage, resistance, impedance, ac-dc difference, and electric power) and some electrical metrology re...

magnetotelluric (mt) method is an important passive surface geophysical method which uses the earth’s natural electromagnetic fields to investigate the electrical resistivity structure of the subsurface. the depth of investigation of mt is much higher than that of other electromagnetic (em) methods (vozoff, 1991). for a general conductivity distribution in the earth, the horizontal electric fie...

Fringing electric and magnetic field sensors are widely used for non-destructive measurements of material properties. A simple conventional fringing field sensor consists of a sensor head, a current or voltage source, an impedance measurement circuit, and data processing/data acquisition capability. The sensor head is usually a patterned array of electrodes or windings on an electrically insula...

In this paper, impedance measurement of electrolyte-insulator-semiconductor (EIS) structure with high spatial resolution was proposed to monitor cell adhesion. The light addressing ability of this work overcomes the geometrical restrict of cell culture on conventional impedance detection devices such as interdigitated electrode (IDE) and electric cell-substrate impedance sensing (ECIS). Instead...

Capacitive electrodes overcome electrode polarization problems and enable noninvasive measurements hence they do not obstruct flow and avoid corrosion, wearing and soiling. However, their impedance is much higher than that of direct contact electrodes and, to reduce it, the measurement frequency must be increased, which worsens the effects of stray interelectrode impedance. In this paper, we an...
