Introduction

This project is designing a researching instrument for testing a new material. The challenge is the researching plan is not clear, so we need to adjust it while the work is keeping going.


Frist phase

Goal:

Design a circuit use PVDF sensor and show the signal from oscilloscope. Let a steel ball fall on the sensor.

Challenge:

  1. The output wave in oscilloscope has too much noise.
  2. There is a clear maximum value on oscilloscope.
  3. The sensor cannot really tell how strong the force add on it. No matter how strong the force add on the sensor, the output wave is similar with each other.

    Advices to adjust:

  4. Replace battery with power source.
  5. Calibrating the Oscilloscope Probe.
  6. Adjust the sensor and steel ball design. Make sure the sensor won’t be broken
  7. Check circuit and replace the broken elements.
