More than 100 years ago, the “4-point-probe method” became the standard for precision resistivity measurements. BUT: Every 4-point measurement projects the resistivity tensor of the specimen onto a single resistance value.
4-point measurements are limited by the exact determination of specimen geometry.
Measurement results change when contacts drift. Tensormeter solves this challenge by measuring the Resistivity Tensor, which makes measurements resilient against geometry changes and provides greater precision.
