To improve the electrical signal output capability of the flexible and wearable sensors, a 0-3 type piezoelectric composite with polydimethylsiloxane(PDMS) as the substrate and lead zirconate titanate (PZT) as the piezoelectric phase is designed and fabricated. The influence of different solid contents on the rheological property of the slurry is investigated. The results show that the viscosity and shear modulus of the slurry increase with the increase of the mass fraction of the Ag-coated PZT. The yield point of the slurry with w(PZT)=38% is 398.1 Pa, which has the best printability. In the electrical signal test, the highest peak-to-peak voltage of the Ag-coated sample is nearly 5 times larger than that of the sample without Ag-coated. Under the bending test conditions, the sample withΔL=7 cm shows a peak-to-peak voltage of 55 mV, which proves that the sample has flexible sensing performance.
