| Abstract Scope |
This research demonstrates a fully functional remote multi-sensing system powered solely by the energy harvested from the mechanical vibration of road traffic using a stacked piezoelectric transducer. The transducer is built using 20mm˟20mm˟2mm PZT ceramics plates. The electric charges from the damped sinusoidal signal of the stacked PZT transducer are collected using a custom-designed energy converter to charge a battery pack that powers the electronic circuit. The developed system consists of passive sensors built from piezoelectric materials and hence do not consume power. The remote sensing system is capable of accurately sensing pressure, the number of times forces are exerted, and temperature. A low-power Bluetooth module is used to transmit sensory data to a nearby Android device. Successful data transmission was achieved to a considerable distance from the system. The power generated from the stacked PZT transducer is sufficient enough to ensure the sustainability of the sensing system. |
