Characterization of Flattenable Corrugated Sensor for Compression Strain

Corrugated structures have various applications in industry, civil engineering, offshore systems, and aerospace because of their excellent energy absorption property. When we use corrugated structures as cushioning or core materials, detecting the structure's condition is essential to reduce post-harvest losses. In addition, thick structures are bulky during transportation. In this research, we added bistability to a corrugated structure by folding and developed a flattenable corrugated compression sensor. We measured the change in resistance during compression tests and investigated the effects of the flattening mechanism on the mechanical properties and performance of the sensor.
