Activity: A Pyroelectric Smart Sensor PVDF-A polymer with many uses

What is a Smart Sensor? We will use the term “Smart Sensor” to refer to systems that employs a sensor device mated to microelectronics. In this activity we will use metal coated PVDF films as our sensor system and a computer will take the place of the microelectronics. The system used in this activity is not engineered to minimize size and power consumption but clearly those would be goals in any widely deployed commercial device.

Preparation for Activity Items Needed: PVDF sensor films; electronic components for circuits A and C (to be described) ; computer with data acquisition hardware/software. Am understanding of Piezoelectric Effect An understanding of Pyroelectric Effect An understanding of the role of molecular structure in determining the piezoelectric properties of PVDF

Discussion Points Why is the b form of PVDF piezoelectric? How is the b form of PVDF Produced? What is the relationship between piezoelectric effect and the pyroelectric effect? What does the infrared spectrum of PVDF tell us about the wavelengths where the pyroelectric properties of PVDF might be most easily observed?

Representations of the molecular structure of the vinylidene difluoride (VD) monomer and of the a and b forms of the PVDF polymer. VD-wire PVDF-a form PVDF-b form VD-space filling

Discussion Points II How can we detect the piezoelectric or pyroelectric effect exhibited by a PVDF film? What is needed in terms of electronic and computer components to produce a smart sensor?

Discussion Points Design a pyroelectic smart sensor system capable of to locating a single person in a room. Design a system which would make a PVDF pyroelectric sensor sensitive to a wide range of wavelengths. What information might be obtained from the voltage rise and decay exhibited on the thermal response curves What can be done to stabilize a PVDF pyroelectric sensor system?
