Thus, expensive vacuum packaging may not be necessary. 8 2 Design and Modeling of Micro-relay Relay Energy Consumption per Operation The energy consumed in switching a relay is supplied by the voltage source which charges/discharges capacitances. These include the capacitance associated with the actuation air gap, εoA/(g-gd), and the fixed parasitic capacitance C. g. due to wire routing). Assuming an area proportionality factor r and an average relay activity factor aavg, the switching energy of a relay can be modeled by Eq.
It has been shown that Q decreases linearly with beam thickness and is independent of beam width and beam length [13, 14]. Therefore, it is reasonable to treat Q as a technology-dependent constant. Also, since α, β and γ saturate quickly for Q values greater than ~1, Q values significantly higher than 1 are not necessary for high performance. In fact, it may be preferable to avoid highQ relay designs to minimize non-ideal switching effects such as contact bounce and long settling time. Thus, expensive vacuum packaging may not be necessary.
