Highly sensitive and fast response strain sensor based on evanescently coupled micro/nanofibers
文献摘要：
Flexible strain sensors play an important role in electronic skins, wearable medical devices, and advanced robots. Herein, a highly sensitive and fast response optical strain sensor with two evanescently coupled optical micro/nanofibers (MNFs) embedded in a polydimethylsiloxane (PDMS) film is proposed. The strain sensor exhibits a gauge factor as high as 64.5 for strain ≤ 0.5％ and a strain resolution of 0.0012％ which corresponds to elongation of 120 nm on a 1 cm long device. As a proof-of-concept, highly sensitive fingertip pulse measurement is realized. The properties of fast temporal frequency response up to 30 kHz and a pressure sensitivity of 102 kPa?1 enable the sensor for sound detection. Such versatilesensorcouldbeofgreatuseinphysiologicalsignalmonitoring,voicerecognitionandmicro-displacementdetection.
