Wearable Systems of Reconfigurable Microneedle Electrode Array for Subcutaneous Multiplexed Recording of Myoelectric and Electrochemical Signals

open access: yesAdvanced Science, EarlyView.
A reconfigurable microneedle electrode array integrated system is developed for minimally invasive and transdermal monitoring of subcutaneous electromyography, reactive oxygen species, and pH values. By assembling discrete thumbtack‐shaped microneedles into an array, the system enables multi‐parameter detection with single‐microneedle resolution.

The Awakening Brain is Characterized by a Widespread and Spatiotemporally Heterogeneous Increase in High Frequencies

open access: yesAdvanced Science, EarlyView.
This work explores the process of morning awakening of the human brain using polysomnography paired with simultaneous stereo‐electroencephalography, a method that provides high spatial and temporal resolution for examining brain activity. Awakening is characterized by an increase in high‐frequency spectral power and connectivity.

Large‐Area Conductor‐Loaded PDMS Flexible Composites for Wireless and Chipless Electromagnetic Multiplexed Temperature Sensors

open access: yesAdvanced Science, EarlyView.
This work demonstrates the first chipless temperature sensing array based on conductor‐loaded composites. They allow multiple items to be simultaneously identified and monitored through multiplexed electromagnetic reflections. The work studies the influence of conductive fillers on the frequency‐domain properties of PDMS, for the first time.

Revealing the Origin and Nature of the Buried Metal‐Substrate Interface Layer in Ta/Sapphire Superconducting Films

open access: yesAdvanced Science, EarlyView.
The origin and nature of metal‐substrate interface layer in Ta/sapphire‐based superconducting films is investigated using synchrotron X‐ray reflectivity and scanning transmission electron microscopy. An intermixing layer, ≈0.65 nm thick containing Al, O, and Ta atoms, is identified at the interface.
