Huang YT, Huang SC, Hsu CC, Chao RM, Vu TK - Sensors (Basel) (2012)

Bottom Line: All of the micro-fabrication was compatible with the standard IC process.Experimental results indicated that the gauge factor of the proposed strain sensor was larger than 4.5, approximately 2.0 times greater than those of commercial gauges.The results also demonstrated that the gauge factor is small when the growth time of SWCNNs is lengthier, and the gauge factor is large when the line width of the serpentine pattern of SWCNNs is small.

ABSTRACT
This study presents a novel flexible strain sensor for real-time strain sensing. The material for strain sensing is single-walled carbon nanonets, grown using the alcohol catalytic chemical vapor deposition method, that were encapsulated between two layers of Parylene-C, with a polyimide layer as the sensing surface. All of the micro-fabrication was compatible with the standard IC process. Experimental results indicated that the gauge factor of the proposed strain sensor was larger than 4.5, approximately 2.0 times greater than those of commercial gauges. The results also demonstrated that the gauge factor is small when the growth time of SWCNNs is lengthier, and the gauge factor is large when the line width of the serpentine pattern of SWCNNs is small.

Mentions: In addition, the wider view of Figure 5 shows the CNNs serpentine pattern. Further, after the micro-fabrication, the device with thermal release tape is placed on the hot plate, and the presented strain sensor is released from the thermal release tape by heating for 1 min at 120 °C. The final flexible nano-carbon network strain sensor is shown in Figure 6.
