• . With increasing bending angle, the output voltage increased. The promising results show that the textile-based piezoelectric sensor developed in this study has a great potential to be used as an angle measuring wearable device for the human body due to its high current density output and flexibility

• increase when the contact area increases. When the contact area is 80 × 80 mm2, VOC and ISC reach up to about 370 V and 9.5 μA, respectively. The S-TENG can be used as a large wearable device. With bigger contact area, more charges and, consequently, higher ISC values are generated. VOC and ISC both
