Abstract
Resistivity is an intrinsic property that determines how strongly electrical current is resisted. Measuring the resistivity of materials is vital for many science and engineering fields. This is easily accomplished with a four-point probe. However, commercial probes can be costly. Using 3-D printing and based on the design in Lu et. al (J. Chem. Educ. 2017), a functional four-point probe has been built at a much lower cost in materials. Additionally, the probe design has been simplified for easier construction and better compatibility with Belmont's 3-D printers. Various substrates including ITO glass were tested and the data was compared to known values using python. The results show that with proper correction factors resistivity can be measured relatively accurately. Not only is this device useful for material research, but also has educational value as an advanced lab project.
