The digital thermometer

open access: yes, 2021
Remote body temperature meter, capable of enabling access depending on the temperature obtained. The basic idea is that the sensor captures the body temperature without any contact and displays it on the screen, the ultrasonic sensor will be responsible for indicating the correct position to which it has to position the person emitting a sound and the ...

Simultaneous Multifrequency Modulated Wireless Information and Power Transfer for a Triboelectronic Monitoring System

open access: yesAdvanced Science, EarlyView.
A ultrasound‐driven triboelectric nanogenerator multi‐frequency modulated simultaneous wireless power and information transmission (US‐TENG‐MF‐SWIPT) system is proposed for various intelligent microsystems, which increases the efficiency of information transmission multiply with almost no reduction in the power transmission efficiency.

Tailored Electro–Magnetic–Porous Multigradient Nanoarchitectonics for Absorption‐Dominated Electromagnetic Interference Shielding and Adaptive Multifunctionality

open access: yesAdvanced Science, EarlyView.
An electro–magnetic–porous multigradient nanofibrous electromagnetic interference (EMI) membrane is fabricated via shear‐induced in situ fibrillation and layer‐by‐layer assembly. Leveraging a multigradient‐induced “impedance matching–polarization–reabsorption” synergistic mechanism, the membrane achieves absorption‐dominated high‐efficiency EMI ...

Temperature Thresholds Govern Microbial‐Mediated Dissolved Organic Carbon Dynamics in Coastal Ecosystems

open access: yesAdvanced Science, EarlyView.
Coastal dissolved organic carbon (DOC) represents one of the largest reduced carbon pools on Earth, and they are influenced by temperature. Across 7.6–35.9 °C ranges, the microbial‐mediated DOC dynamics is characterized by three temperature thresholds.

Wavelength Tunable Pulsed Lasers Enabled by a Versatile Metafiber Functioning as Both Saturable Absorber and Filter

open access: yesAdvanced Science, EarlyView.
Schematic diagram of wavelength‐tunable pulsed laser based on metafiber‐FP (Fabry‐Perot). The alcohol solution is filled inside the FP cavity to simultaneously form a spectral filter and a saturable absorber. By adjusting the refractive index value and temperature inside the cavity, the tunable filtering effect is introduced to realize wavelength ...
