Figure 1

Basic idea behind CIT-TENG. (a) Conceptual illustration showing that CIT-TENG can continuously scavenge broadband frequency vibrations from multiple ambient sources. (b) Photograph of actual CIT-TENG developed in this work. (c) Cross-section schematic of CIT-TENG design and the cascade impact behavior initiated by activated TENG-1. (d) Voltage output frequency response of typical tandem TENG showing non-continuous scavenging at input acceleration of 0.2 G m/s2. (d) Voltage output frequency response of CIT-TENG showing continuous scavenging within 40 Hz bandwidth at input acceleration of 0.2 G m/s2.
