Neurophysiological correlates of the rubber hand illusion in late evoked and alpha/beta band activity [PDF]

open access: yes, 2017
The rubber hand illusion (RHI) allows insights into how the brain resolves conflicting multisensory information regarding body position and ownership. Previous neuroimaging studies have reported a variety of neurophysiological correlates of illusory hand

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Hand-Arm Vibration Syndrome Associated with Impact Vibration

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 1995
The data from 141 hand-arm vibration exposed workers examined for hand-arm vibration syndrome (HAVS) was analyzed in a Cox regression model to determine whether smoking, alcohol, the use of gloves, duration of weighted vibration exposure, and vibration impulsiveness affected the rate of onset of Raynaud's phenomenon. The results show that workers with

Chemically Doped Conductive Polymers for Wearable Health Monitoring

open access: yesAdvanced Materials Technologies, EarlyView.
Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.
