The purpose of this study is to develop mechanical energy harvesting systems using piezoelectric materials for a wireless sensor node. This system is composed of piezoelectric material for mechanical energy harvesting, a power management circuit, an energy storage and a wireless sensor node. Testing shows that a sensor node can transmit a packet every 2.77 seconds or sleep 16.24 seconds interval with a piezoelectric plate attached with a 10-gram mass at the tip. Therefore, the piezoelectric plate is capable of providing the power for a sensor node.
