electrocorticogram (ECoG) recording and retinal prosthesis, involve electrical interactions with soft …

Implementing neural architectures using analog VLSI circuits

MAC Maher, SP Deweerth… - IEEE transactions on …, 1989 - ieeexplore.ieee.org
Analog very large-scale integrated (VLSI) technology can be used not only to study and
simulate biological systems, but also to emulate them in designing artificial sensory systems. A …

A multiconductance silicon neuron with biologically matched dynamics

…, RL Calabrese, SP DeWeerth - IEEE Transactions …, 2004 - ieeexplore.ieee.org
We have designed, fabricated, and tested an analog integrated-circuit architecture to
implement the conductance-based dynamics that model the electrical activity of neurons. The …

A lithographically-patterned, elastic multi-electrode array for surface stimulation of the spinal cord

…, RJ Giuly, L Guo, S Hochman, SP DeWeerth - Biomedical …, 2008 - Springer
A new, scalable process for microfabrication of a silicone-based, elastic multi-electrode
array (MEA) is presented. The device is constructed by spinning poly(dimethylsiloxane) (PDMS) …

Novel nonlinear elastic actuators for passively controlling robotic joint compliance

SA Migliore, EA Brown, SP DeWeerth - 2007 - asmedigitalcollection.asme.org
The ability to control compliance of robotic joints is desirable because the resulting robotic
mechanisms can adapt to varying task requirements and can take advantage of natural limb …

Stimulus-artifact elimination in a multi-electrode system

…, Y Nam, BC Wheeler, SP DeWeerth - IEEE transactions on …, 2008 - ieeexplore.ieee.org
