Consequently, the device exhibits rapid electromechanical transduction with an ultrashort pulse duration of 500 \u00b5s, alongside high output voltage and power. Integrated onto the human body, the sensor delivers sensitive, repeatable responses to various biomechanical motions. Beyond tactile sensing, the device enables high\u2010fidelity acoustic detection and intelligent signal analysis. By implementing harmonic evaluation and principal component analysis, the system achieves reliable discrimination among musical instruments with distinctive spectral fingerprints. Collectively, this work establishes the freestanding PZT film as a multifunctional platform integrating energy harvesting and intelligent acoustic\u00a0recognition, offering new pathways for self\u2010powered biointegrated electronics.\n
