Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...

“BURNS CAUSED BY ELECTRICITY”. (A Review of one hundred cases)

open access: yesIndian Journal of Plastic Surgery, 1981
Hundred cases of electrical burn have been studied. Young males adults were found to be more affected and the percentage of burn in most of the cases were rather low. High tension injury was the cause in majority of the cases.
