In nuclear electronics, a microstrip detector is a particle detector that consists of a large number of identical semiconductor strips laid out along one axis of a two-dimensional structure, generally by lithography. The geometrical layout of the components allows to accurately reconstruct the track of an incoming particle of ionizing radiation.

Silicon microstrip detectors are a common design used in various particle physics experiments.{{cite journal |last1=Resmi|first1=P.K. |collaboration=BELLE collaboration |display-authors=etal |year=2018 |title=Construction and quality assurance of the Belle II Silicon Vertex Detector |arxiv=1901.09549}}{{cite journal |last1=Liang|first1=Z. |collaboration=ATLAS collaboration |display-authors=etal |year=2018 |title=Construction of the new silicon microstrips tracker for the Phase-II ATLAS detector |journal=Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment |volume=924 |pages=265–269 |doi=10.1016/j.nima.2018.09.014 |arxiv=1804.10771|s2cid=118885150 }} The detection mechanism consists of the production of electron-hole pairs in a layer of silicon a few hundreds of micrometers thick. The free electrons are drifted by an electric field created by a pattern of anodes and cathodes interdigitated on the surface of the silicon and separated by a {{chem2|SiO2}} insulator.
