Figure 8. Application demonstration of catheters equipped with miniature tactile sensors. (A) Lung model used to test a medical catheter with bilateral pressure sensing capability (left part) and corresponding pressure signals obtained by the two sensors inside the left lobar branch of the lung (right plot)[11]. (B) In vivo measurement of the oral airflow in rats using a flow sensing catheter (left part) and extracted heartbeat signals from the airflow waveform at a rat’s mouth (right plot)[12].
