Abstract

Wearable Internet of Things (IoT) devices for sports require an innovative design of a self-powered technology that is able to wirelessly transmit and receive the signal (force, ambient condition) forms a body wearing item, relying upon the vibration/impact energy harvesting materials that possess lightweight but excellent resistance to intense exercise. In this study, piezoelectric hybrid carbon fiber reinforced polymer (CFRP) composite laminates are developed by embedding potassium sodium niobate (KNN) nano-particle filled epoxy interlayer, and the composite samples are successfully polarized. The output voltage of the samples due to impact load is then measured. The results show that a voltage higher than 50 mV is generated. Our work represents an important step forward in the development of piezoelectric CFRP composite materials for energy harvesting applications and opens the door for further development of lightweight, robust and efficient energy harvesting sport equipment.
