Fig. 2: The in vitro output performance of different TENGs and the response of TRI-TENG to different stimuli.
From: E-cardiac patch to sense and repair infarcted myocardium
A The performance of different TENGs with different components in the open-circuit voltage (VOC), short-circuit current (ISC), and transferred charges (n = 5 independent samples). B Output voltage, power density, and current of different TENGs at different load resistance. C Voc of TRI-TENG at different frequencies, pressure, and strains. D Demonstration of the TRI-TENG detecting different mechanical motions. The TRI-TENG is attached to the throat for detecting speaking, coughing, and swallowing; attached to the fingers for detecting finger joint movements; and attached to the ankle for detecting walking, running, and jumping. Statistical significance in sample of VOC was calculated using two-side one-way ANOVA with Dunnett’ s post hoc test, and statistical significance in sample of ISC and transferred charges was calculated using two-side one-way ANOVA with LSD post hoc test.
