Kinetic energy harvesters (KEH) or motion energy harvesters currently become an attractive trend as a selfsustainable power solution of Internet of Things (IoT) devices. As utilizing the ambient motion as the power source, KEH can be treated as a gait information carrier as well as a energy generator. This work focuses on exploiting gait information, carried by one type of KEH: piezoelectric energy harvesters (PEHs), to develop a communication key scheme. The key coding scheme is based on quantization of captured samples. The results show that the system can work in a narrowed experimental environment.
