A Review of Printable Flexible and Stretchable Tactile Sensors

Figure 2

Schematic illustration of flexible (F) and stretchable (S) printed elements. The dotted lines represent the neutral line. (a) Flexibility defined as the bendability and the deflecting ability of the sensor from the plane with a radius of curvature, . represents the deflection of the sensor from the neutral line. (b) The longitudinal strain caused by stretching increases the length of the printed FSE along the direction of load, while the lateral strain caused by stretching decreases the dimension perpendicular to the direction of load.
