摘要：

The sensitivity of a nanoscale crack-based sensor is enhanced markedly by modulating the crack depth. The crack-depth-propagated sensor exhibits approximate to 16 000 gauge factor at 2% strain and a superior signal-to-noise ratio of approximate to 35, which facilitates detection of target signals for voice-pattern recognition.
