Effect of thermal modification in the natural resistance of Eucalyptus grandis and Pinus taeda woods

Revista Brasileira de Ciências Agrárias - Brazilian Journal of Agricultural Sciences, 2019
The aim of the study was to evaluate the natural durability of wood submitted to heat treatments and exposed in a field environment. Were used Eucalyptus grandis and Pinus taeda species, being selected five trees selected for each species studied, which were unfolded, dried in a conventional drying kiln, and later submitted to the heat treatments using

Skin‐Like Tri‐Modal Sensors Based on Soft Piezoelectric and Ionic Composites

Advanced Materials Technologies, EarlyView.
Inspired by the multimodal perception of human skin, a soft, skin‐like tri‐modal sensor is presented. The device incorporates an ionically conductive, piezoelectric, elastic composite as its active layer, enabling independent detection of temperature, static strain, and dynamic strain within a single two‐terminal architecture.
