Abstract

For the first time ever, we demonstrate an Epi-Seal encapsulated, self-excited Franklin oscillator. This electromechanical switch oscillator, is driven by a constant input of 3.8 [V], sustains self-oscillations at a frequency of 88.6 [kHz], and requires a power of only 1.5 [mu mathrm{W} {mathrm{RMS}}]. We demonstrate over 200 million switching cycles, with two events of contact/charge transfer in each cycle. We demonstrate that a high mechanical restoring force is crucial for long-term reliability of switch oscillators. Furthermore, we implement a new driving scheme that further increases the long-term reliability. The relevance of this device is its potential as a new concept for a low cost, low power, wafer level MEMS oscillator.
