Micropatterned Biphasic Printed Electrodes for High‐Fidelity on‐Skin Bioelectronics

Advanced Functional Materials, EarlyView.
Micropatterned biphasic printed electrodes achieve unprecedented skin conformity and low impedance by combining liquid‐metal droplets with microstructured 3D lattices. This scalable approach enables high‐fidelity detection of ECG, EMG, and EEG signals, including alpha rhythms from the forehead, with long‐term comfort and stability.

Multiphase MCMC sampling for parameter inference in nonlinear ordinary differential equations [PDF]

, 2018
Traditionally, ODE parameter inference relies on solving the system of ODEs and assessing fit of the estimated signal with the observations. However, nonlinear ODEs often do not permit closed form solutions. Using numerical methods to solve the equations

Parameter Estimation of Multiphase Machines Applicable to Variable Phase-Pole Machines

2022 International Conference on Electrical Machines (ICEM), 2022
Variable phase-pole machines are envisioned in applications requiring a large torque-speed operating area. The control of these machines relies on accurate models and parameters but research on parameter identification methods is scarce. This paper presents an offline parameter-identification method for variable phase-pole machines adopting a harmonic ...
