The PDMS micropillar arrays are fabricated using laser\u2010ablated through\u2010hole molds. The micropillar tips preferentially deform under subtle stimuli, whereas the base layer is progressively engaged under increasing loads. This hierarchical deformation mechanism enables continuous resistance modulation over a broad pressure range. Consequently, the sensor delivers a sensitivity of 103 kPa\n                    <jats:sup>\u2212<\/jats:sup>\n                    <jats:sup>1<\/jats:sup>\n                    over a wide detection range of 0.6\u2013588\u00a0kPa, together with fast response\/recovery times (6\/20\u00a0ms) and robust cyclability (10,000 cycles). Beyond physiological monitoring, the sensor further enables acoustic\u2010vibration detection from the Erhu, a traditional Chinese bowed instrument. Assisted by a one\u2010dimensional convolutional neural network (1D\u2010CNN), a pitch recognition accuracy of 97.5% is achieved. This work provides a structural design strategy for high\u2010performance piezoresistive sensors and establishes a new paradigm for intelligent recognition and acoustic\u2010based human\u2013machine
