Figure 7

(a) TEH output voltage waveform at different sinusoidal acceleration measured at dwell frequency of 82 Hz. (b) TEH short circuit current waveform at different sinusoidal acceleration measured at dwell frequency of 82 Hz. (c) Linear relation observed between TEH outputs and applied acceleration with voltage and current sensitivity of 4.7 Vg−1 and 19.7 nAg−1, respectively.
