Effect of dispersive conductivity and permittivity in volume conductor models of deep brain stimulation

Grant, Peadar F. ; Lowery, Madeleine M. (IEEE, 2010-10)

The aim of this study was to examine the effect of dispersive tissue properties on the volume-conducted voltage waveforms and volume of tissue activated during deep brain stimulation. Inhomogeneous finite-element models ...
Dielectric charge control in electrostatic MEMS positioners / varactors

Blokhina, Elena ; Lopez, David ; Gorreta, Sergi ; Molinero, David ; Feely, Orla ; Pons Nin, Joan ; Dominguez, Manuel (IEEE, 2012-02-06)

A new dynamical closed-loop method is proposed to control dielectric charging in capacitive MEMS positioners/ varactors for enhanced reliability and robustness. Instead of adjusting the magnitude of the control voltage to ...
Pulsed Digital Oscillators for Electrostatic MEMS

Fernandez, D. ; Jimenez, V. ; Madrenas, J. ; Gorreta, Sergi ; Blokhina, Elena ; Pons Nin, Joan ; O'Connell, Diarmuid ; Feely, Orla ; Dominguez, Manuel (IEEE, 2012-07-25)

This paper introduces a new actuation scheme for implementing Pulsed Digital Oscillators (PDOs) for electrostatic MEMS resonators. In this scheme, the capacitance of the device is biased with a voltage and it is periodically ...
