– Piezoelectric gastrointestinal motility sensor (Fig. 1)
v. 12 groups in series, 10 groups in parallel. (Fig. 2)
v. Sensing principle: piezoelectric material (Fig. 3)
v. Live/dead cytotoxicity analysis of HT-29-MTX-E12, HeLa and C2BBe1 cells incubated with neutralized simulated gastric fluid for three days.
v. Cells treated with 70% ethanol were used as a negative control.
v. Cells treated with neutralized gastric fluid that had not been in contact with the microchips were used as a positive control
v. Green indicates viable cells and red indicates dead cells. (Fig. 4)
