Modeling & Characterizing Stochastic Actuator Arrays
(Georgia Institute of Technology, 2009-10)
If the modal response for a single degree of freedom flexible system is known, a command generation architecture can be determined which schedules on/off actuator effort such that the resulting motion will have zero ...
Large Effective-Strain Piezoelectric Actuators Using Nested Cellular Architecture with Exponential Strain Amplification Mechanisms
(Georgia Institute of Technology, 2010-10)
Design and analysis of piezoelectric actuators having over 20% effective strain using an exponential strain amplification mechanism are presented in this paper. Piezoelectric ceramic material, such as lead zirconate titanate ...
Wearable Sensorimotor Enhancer for a Fingertip based on Stochastic Resonance
(Georgia Institute of Technology, 2011-05)
This paper reports the initial experimental results of a wearable sensorimotor enhancer for a fingertip. A shorttime exposure of tactile receptors to sub-sensory white-noise vibration is known to improve the tactile ...
