Abstract

Laser decal transfer based µ-3D printing is a new technique for microscale fabrication of the MEMS devices. The freedom towards the thin metal film, polymers, biomolecules, nanoparticles set off the new direction for fabrication of sensors and actuators. In this work, a NiTi based strain sensor is printed on PET substrate using µ-3D printing. Three and five-layer of strain gauge are printed, and its response are analysed by tensile loading. The resistance of the printed strain gauge are 220 ± 10 kΩ and 88 ± 8 kΩ while the gauge factor found to be 9 ± 3 and 13.5 ± 1.5 respectively.
