The piezoresistive effect is given by (1 2 ) R R (1) where is the resistivity of the piezoresistor‚ depends on the doping concentration of the piezoresistors‚ ν is the Poisson’s ratio and is the mechanical strain induced in the diaphragm. The first part of the left hand side of equation 1 describes the piezoresistive effect and the second part defines the geometric effect. For piezoresistive materials like polysilicon‚ the piezoresistive effect dominates over geometric effect

Every single day we use electricity to make the things around us work. From the tape player to the electric pumps that send hot water to each of our homes everyday. Without electricity the lights go off‚ water is not heated‚ the television goes off‚ and outside the traffic lights do not work and as a result the city is immediately congested with traffic jams and choke ups in the street. Without that electricity we have everyday the basic things we use do not function. The book I chose to summarize

EQUIPOTENTIAL SURFACES COMPUTER LAB ACTIVITY Name:__ ________________________ Remember that an equipotential surface is the set of all points around a group of charges that are at the same potential. Hese surfaces allow us to calculate the amount of work needed to move a charge from one spot to another. The amount of work needed to move a charge q through a potential difference ΔV is given by: W=qΔV The purpose of today’s activity is to make you familiar with the shape and appearance of these
