Investigation of mechanical energy harvesting cycles using ferroelectric/ferroelastic switching
- Abstract:
- Piezoelectric energy harvesters have been widely developed in last decade due to their simplicity and practicality, but they suffer from low energy density. To increase the energy density, ferroelectric/ferroelastic switching could be an effective alternative energy harvesting approach. However, the nonlinearity and irreversibility of ferroelectric switching produces difficulty in establishing a stable working cycle. In this work, novel, practical and stable energy harvesting cycles using ferroelectric/ferroelastic switching are established and explored under quasi-static experimental conditions. A prototype device with a simple ‘sandwich’ configuration is tested. The results show that the cycle energy density can reach 11 mJ/cm3 under tensile loading and 3.2 mJ/cm3 under compression, demonstrating great potential for practical applications.
