| Abstract [eng] |
In this research, a novel piezoelectric impact energy harvester, intended for high frequency burst-type signal generation using horn-type waveguide as resonator of particular frequency, which increases the amplitude of generated burst-type signal and protects the brittle piezoceramic material from breakage due to by impact is designed. Such a device allows to drive and control an ultrasonic motor in environments where traditional power supplies, such as power supply or batteries are unavailable or when they are damaged. In this work horn-type waveguide was investigated in different way – with harmonic and impulse excitation on the surface with a smaller cross-sectional area thus allowing to uniformly transmit the impact energy to piezoelectric transducer with a surface of greater cross-sectional area. |
