Simultaneous Large Optical and Piezoelectric Effects Induced by Domain Reconfiguration Related to Ferroelectric Phase Transitions

Advanced Materials, Volume 34, Issue 7, February 17, 2022., 2022
In domain‐engineered relaxor ferroelectric crystals of Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3, reversible and repeatable phase transitions from the as‐poled polydomain rhombohedral state to a monodomain monoclinic state can be stimulated by electric field or stress. These transitions lead to bimodal functionality—variable optical transparency as well

Piezoelectric energy harvesting for self‐powered wearable upper limb applications

Nano Select, Volume 2, Issue 8, Page 1459-1479, August 2021., 2021
Upper limbs provide enormous potential for harvesting mechanical energy from the human body during daily movements. This paper systematically reviews a range of piezoelectric energy harvesters for powering wearable devices that are mounted on the upper limb. Accordingly, maximum power density can be achieved on the wrist.
