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

open access: yesAdvanced 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.

Double Helical Plasmonic Antennas

open access: yesAdvanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Investigating the variation of intonation contours in Northern Vietnamese tones

open access: yesFrontiers in Education
Intonation is an instrument for structuring discourse and emphasizing different types of information. In German, for example, pitch is used to highlight focus, while in Vietnamese, different pitch contours distinguish lexical tones.

Some Considerations on Pitch

open access: yesPhenomenology and Mind, 2016
Pitch is an audible quality of sound which can be explained not only in terms of strong correlation with sound waves’ properties, but also by a neat correlation to the properties of the sounding object.
