To better tailor the circuit to your needs, I have one clarifying question:
  1. Do you intend to process the piezo sensor's signal using a microcontroller (with amplification and filtering stages) for digital heart rate measurement, or are you looking for a simpler, entirely analog circuit (using op-amp amplification, filtering, and possibly a direct indicator like an LED)?
Please let me know your preference.
Digital circuit with MCU.
Simple analog circuit.
Hybrid design approach.
