The invention discloses a quantitative detector for sensory nerves and a piezoelectric material used in the quantitative detector for the sensory nerves. The quantitative detector for the sensory nerves comprises a processor control unit, a digital-to-analog conversion unit and an output unit. The processor control unit is used for controlling the digital-to-analog conversion unit to conduct digital-to-analog conversion and controlling the output unit to output vibration of a specified frequency. The digital-to-analog conversion unit is used for digital-to-analog conversion. The output unit is used for outputting the vibration of the specified frequency. The output unit comprises a stimulator driving circuit and a piezoelectric vibration simulator. The stimulator driving circuit is used for driving the piezoelectric vibration simulator to output vibration according to the output vibration information. A piezoelectric layer of a piezoelectric element in the piezoelectric vibration simulator is made of a piezoelectric polymer material. The piezoelectric polymer material is a FeCl3/nano BaTiO3 particle/silicone resin composite material. By the adoption of the quantitative detector for the sensory nerves and the piezoelectric material of the quantitative detector, the piezoelectric material used in the quantitative detector for the sensory nerves integrates the good tensile performance and the good flexibility.
