Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

Advanced Materials, EarlyView.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Pain Threshold in Workers with Vibration Induced White Finger

Nippon Eiseigaku Zasshi (Japanese Journal of Hygiene), 1975
In vibration disease there is the peripheral nerve disturbances (sensory disturbances) of fingers. To detect the sensory disturbances the vibratory sense threshold and the pain threshold and so on have been measured.This paper discribes observations on the change of the pain threshold of the finger before and after cold exposure i.e., immersion of the ...

Vibration related white finger disease: a case report

, 2018
Vibration related white finger disease is frequently observed in workers exposed to hand-arm vibration. The main occupational exposure sources for hand-arm vibration are grinding, road and concrete breaking, using of grinding wheel, rotary saw, high ...

The development of a new artificial model of a finger for assessing transmitted vibrations. [PDF]

, 2018
Prolonged exposure of the hand to tool-induced vibrations is associated with the occurrence of conditions such as vibration white finger. This study involves the development of a new artificial model that approximates both loading and vibration behaviour

Stable Protein‐Based G‐Quadruplex‐Derived Supramolecular Bioinks as Tunable ECM‐Mimetic Constructs Assembled by Combining Non‐Covalent and Covalent Strategies

Advanced Materials, EarlyView.
Harnessing the synergistic interplay of supramolecular self‐assembly, under macromolecular crowding conditions, and enzymatic‐mediated covalent crosslinking toward a stable protein‐based G‐quadruplex‐derived supramolecular bioink. This bioinspired strategy enables the biofabrication of complex and tunable ECM‐mimetic constructs, providing a platform ...

Prognosis of vibration induced white finger: a follow up study. [PDF]

Occupational and Environmental Medicine, 1995
OBJECTIVES--To follow up 102 patients with vibration induced white finger (VWF). METHODS--102 subjects with VWF were reexamined one to 13 years after the condition had first been diagnosed. Information about symptoms, occupation, vibration exposure, smoking habits, age, and the prevalence of other diseases was present in the medical records from the ...
