We propose the use of electrostatic force feedback to control the effective mass, damping, or
stiffness of micro electro mechanical system (MEMS). Our analysis suggests that if feedback …

Vibration-based sensing modalities traditionally have relied upon monitoring small shifts in
natural frequency in order to detect structural changes (such as those in mass or stiffness). In …

Resonance is known to reduce the input energy requirements of various actuator systems.
The favorable effects of resonance, however, are limited to a narrow frequency range. To …

The field of coupled resonant systems is a rich research area with enumerable real-world
applications, including the fields of neural computing and pattern recognition, energy …
