A wearable article, a system, and methods include a structural material configured to be worn on a body, a volatile energy storage device, a wireless transmission circuit, coupled to the volatile energy storage device, comprising an antenna having a minimum transmission energy, a kinetic energy generator, positioned with respect to the structural material in a configuration to be manipulated to induce a voltage output, the kinetic energy generator coupled to and configured to charge the volatile energy storage device, a sensor configured to output activity data related to the wearable article, and an electronic data storage, coupled to the sensor, configured to store the activity data. Upon the volatile energy storage device charging to at least the minimum transmission energy, the wireless transmission circuit transmits the activity data as stored in the electronic data storage based on energy discharged from the volatile energy storage device. |
