Electrostatic Measurement of E.M.F

Characteristics, Dosimetry & Measurement of Emf

This paper describes characteristics of electromagnetic fields and their interaction with body as a fundamentals of electromagnetic field (EMF) safety issue. It also presents how engineering and physics contribute to this. EMF should be appropriately and precisely characterized when we consider its interaction with body. Dosimetry, which is the quantification of substance interacting with the e...

Automation of Electrostatic Material Property Measurement Procedures

The design of released microstructures depends on accurate knowledge of residual stresses and associated elastic constants. The MIT-developed material test procedure, M-Test, uses the variation of pull-in voltage with beam length to extract residual stress and elastic modulus from in-situ test structures. This thesis reports a fully automated computer-microvision procedure that automatically de...

An electrodynamic sensor for electrostatic charge measurement

Electrodynamic sensors are used in the process industry because they are low cost and robust. Though frequently used very little fundamental work on them has been reported. This paper describes an investigation into characteristics of hemispherically and rectangularly shaped sensors. Two parameters are investigated, the effect of sensor area on sensitivity and the spatial filtering effect of th...
