An Implantable Piezofilm Middle Ear Microphone: Performance in Human Cadaveric Temporal Bones

no code implementations22 Dec 2023 John Z. Zhang, Lukas Graf, Annesya Banerjee, Aaron Yeiser, Christopher I. McHugh, Ioannis Kymissis, Jeffrey H. Lang, Elizabeth S. Olson, Hideko Heidi Nakajima

The equivalent input noise (0. 1-10 kHz) of the DrumMic and amplifier referenced to the ear canal was measured to be 54 dB SPL and estimated to be 46 dB SPL after accounting for the pressure gain of the outer ear.

PPR: Physically Plausible Reconstruction from Monocular Videos

no code implementations ICCV 2023 Gengshan Yang, Shuo Yang, John Z. Zhang, Zachary Manchester, Deva Ramanan

Given monocular videos, we build 3D models of articulated objects and environments whose 3D configurations satisfy dynamics and contact constraints.

Fast Aquatic Swimmer Optimization with Differentiable Projective Dynamics and Neural Network Hydrodynamic Models

no code implementations30 Mar 2022 Elvis Nava, John Z. Zhang, Mike Y. Michelis, Tao Du, Pingchuan Ma, Benjamin F. Grewe, Wojciech Matusik, Robert K. Katzschmann

For the deformable solid simulation of the swimmer's body, we use state-of-the-art techniques from the field of computer graphics to speed up the finite-element method (FEM).

Computational Efficiency

Sim2Real for Soft Robotic Fish via Differentiable Simulation

no code implementations30 Sep 2021 John Z. Zhang, Yu Zhang, Pingchuan Ma, Elvis Nava, Tao Du, Philip Arm, Wojciech Matusik, Robert K. Katzschmann

Accurate simulation of soft mechanisms under dynamic actuation is critical for the design of soft robots.

DiffAqua: A Differentiable Computational Design Pipeline for Soft Underwater Swimmers with Shape Interpolation

no code implementations2 Apr 2021 Pingchuan Ma, Tao Du, John Z. Zhang, Kui Wu, Andrew Spielberg, Robert K. Katzschmann, Wojciech Matusik

The computational design of soft underwater swimmers is challenging because of the high degrees of freedom in soft-body modeling.
