The propose of this paper is to extend the microeconomic benchmarking approach known as "technometrics". We offer a novel approach to measuring technical change at the product level, based on intertemporal comparison of product characteristics, using objective performance measures. The goal of the study is to provide a straightforward tool for benchmarking technological sophistication that can be portrayed graphically and shows how technological capabilities have changed between two points in time. This paper extends the static analysis of a previous paper, as it again deals with sensors, and implements the dynamic technometric approach on the updated sensor data.
