More superior pyroelectric performance of synthesized dravite by high-pressure solid-state method

AIP Advances, 2019
It’s of great significance to explore the synthesis of tourmaline with simple chemical composition to study the mechanism of its pyroelectric properties due to the presence of crystal defects and isomorphous substitution in natural tourmaline.

Portable Breathing Monitoring With Phase‐Resolved Airflow Dynamics Enabled by a Dual‐Response Flexible PZT Sensor

Advanced Healthcare Materials, Volume 15, Issue 25, 3 July 2026.
A portable respiratory monitoring device based on a flexible PZT sensor captures pressure‐ and temperature‐related airflow responses in a single waveform. Polarity‐opposed piezoelectric and pyroelectric components generate a narrow transient spike and a broad quasi‐steady peak during both inhalation and exhalation. This dual‐component structure enables

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Embedded Direct‐Written Organic Micro‐TEGs for High‐Efficiency Skin‐Heat Harvesting

Advanced Electronic Materials, Volume 12, Issue 13, 6 July 2026.
A finite‐element–guided design of direct‐written organic micro‐thermoelectric generators is presented for efficient skin‐heat harvesting. Embedding PEDOT:PSS/PBFDO thermoelectric legs within flexible substrates suppresses interfacial heat losses and enhances vertical heat flow.
