Piezouporovna merilna zaznavala izdelana z metodo 3D tiska prinašajo nove rešitve pri aplikaciji zaznaval v oblikovno strukturo. Električne lastnosti prevodnih polimerov še niso dovolj raziskane, da bi se polimerna piezouporovna zaznavala lahko uporabljala v razširjenem obsegu. Magistrsko delo obsega teoretične osnove piezouporovnih zaznaval in materialov primernih za izdelavo le teh. Opisan je potek merjenja cikličnih obremenitev 3D natisnjenega senzorja upogiba s klasificiranimi premori ter primerjava karakteristik večih preizkušancev med seboj.

• Title: Measurement of the effect of cyclic loading on the response of a 3D printed displacement sensor

Abstract

Piezoresistive sensors made with the 3D printing method bring new solutions in the application of sensors in the design structure. The electrical properties of conductive polymers have not been sufficiently investigated to allow polymer piezoresistive sensors to be used on an extended scale. The master's thesis comprises the theoretical foundations of piezoresistive sensors and materials suitable for their manufacture. The course of measuring the cyclic loads of a 3D printed bending sensor with classified pauses is described, as well as a comparison of the characteristics of several test specimens with each other.
