This diploma thesis presents development of a penetration force measurement system with movement control. The system enables the user to perform controlled movements of the measurement head in 5 μm increments with simultaneous measurement of exerted force on an object. Presented system can be implemented in various fields of application, such as plant penetration force detection in biology as well as in insulin micro dosing systems. The aim of this work is to present a small, portable and autonomous system, comprised of control electronics with housing, a stepper motor, LCD display, piezoelectric sensor and mechanical framework. This thesis presents the development of system components, with emphasis on design and implementation of control electronics with piezoresistive force sensor. Finally, the performed test results of penetration force are described.
