Measuring pulse wave technology has received great attention because it indicates the status of the heart and blood vessels. For measuring precise pulse wave, high sensitivity (gauge factor〉500) at low deformation (〈1% strain) and repeatability are necessary. Because a pulse of blood causes micro-scale deformation of skin, high sensitivity sensor is required to measure the small deformation. However, other studies are low sensitivity under 1% strain and poor hysteresis that makes unreliable repeatability. Here, we fabricated a crack-based strain sensor that has high sensitivity (Gauge Factor〉2,000) at low strain (〈1% strain) with pre-strain (P.S) and sensor extending (S.E) process. We can also control sensitivity and linearity through P.S and S.E as needs.
