We analyzed the response of a symmetric electret parallel-plates actuator. We show that the displacement is a linear function of driving voltage, and that a full range of stable motion can be achieved. Furthermore, all important characteristics of the fixed charge can be deduced from simple measurements.

There is a growing interest in using charged floating electrodes as an alternative for dc bias voltage in microsystems. How do you monitor charge retention in a floating electrode without discharging it?

We demonstrate a non-disruptive measurement of charge retention on floating electrodes.

Curved fonts, drastically inflate the size of layout files. Also, when text is etched in SOI, bits of letters fly off during BOX release.
To overcome both issues I have designed the DEPLOF font - which I am the first to admit is profoundly ugly.
