3-D imaging using row-column-addressed arrays with integrated apodization - part i: apodization design and line element beamforming
TL;DR: The line element beamforming approach is shown to be essential for achieving correct time-of-flight calculations, and hence avoid geometrical distortions.
Journal ArticleDOI
3-D imaging using row–column-addressed arrays with integrated apodization— part ii: transducer fabrication and experimental results
Thomas Christiansen,Morten Fischer Rasmussen,Jan Peter Bagge,Lars Nordahl Moesner,Jørgen Arendt Jensen,Erik Vilain Thomsen +5 more
TL;DR: The fabrication, characterization, and experimental imaging results of a 62+62 element λ/2-pitch row- column-addressed capacitive micromachined ultrasonic transducer (CMUT) array with integrated apodization, designed to reduce the amplitude of the ghost echoes that are otherwise prominent for row-column-add addressed arrays, are demonstrated.
Journal ArticleDOI
An Electronic Patch for Wearable Health Monitoring by Reflectance Pulse Oximetry
R.G. Haahr,S. B. Duun,Mette Helene Toft,Bo Belhage,Jan Larsen,Karen Birkelund,Erik Vilain Thomsen +6 more
TL;DR: The Electronic Patch is demonstrated with a new optical biomedical sensor for reflectance pulse oximetry so that the Electronic Patch in this case can measure the pulse and the oxygen saturation.
Journal ArticleDOI
Screen printed PZT/PZT thick film bimorph MEMS cantilever device for vibration energy harvesting
Ruichao Xu,Anders Lei,Thomas Christiansen,Karsten Kryger Hansen,Michele Guizzetti,Karen Birkelund,Erik Vilain Thomsen,Ole Hansen +7 more
TL;DR: In this article, a MEMS-based PZT/PZT thick film bimorph vibration energy harvester with an integrated silicon proof mass is presented, which replaces the support with another layer of the piezoelectric material, and with the absence of an inactive mechanical support all of the stresses induced by the vibrations will be harvested by the active PZE elements.
Proceedings ArticleDOI
A wearable “electronic patch” for wireless continuous monitoring of chronically diseased patients
TL;DR: An electronic patch where sensors, low power electronics, and radio communication are integrated in an adhesive material of hydrocolloid polymer making it a sticking patch for non-invasive and wireless monitoring of physiological signals is presented.
