我们描述了最近的努力，由不同的团体在实现电阻电极的微型气体检测器的目的是联合收割机在同一设计的电阻板室（RPC）的最佳功能-例如，其鲁棒性和火花保护性能-与高粒度，从而提供了良好的位置分辨率的微电子技术。在这一活动的流中，我们最近开发了两种新型的电阻电极探测器;一个基于电阻微网，第二个是一个微带气室与电阻电极。我们已经证明，电阻网格是一个方便的结构元素，用于各种设计的火花保护探测器，例如平行板或微图案类型。这些新的探测器使得RPC和微图案探测器应用的显著增强成为可能，因为它们不仅具有高的位置分辨率，而且具有相对良好的能量分辨率（在6 keV和半峰处的25-30%全宽），并且如果必要的话，它们可以以级联模式操作，从而允许实现高的总体气体增益。
We describe the most recent efforts made by various groups in implementing resistive electrodes in micropattern gaseous detectors with the aim to combine in the same design the best features of Resistive Plate Chambers (RPCs)—for example, their robustness and spark-protection property—with the high granularity and thus the good position resolution offered by microelectronic technology. In the stream of this activity, we have recently developed two novel detectors with resistive electrodes; one based on resistive micromeshes and the second one is a microstrip gas chamber with resistive electrodes. We have demonstrated that the resistive meshes are a convenient construction element for various designs of spark-protective detectors, for example of parallel-plate or micropattern types. These new detectors enable considerable enhancement of the RPC and micropattern detectors applications since they feature not only high position resolution but also relatively good energy resolution (25–30% full width at half maximum and at 6keV) and, if necessary, they can operate in the cascaded mode, allowing the achievement of a high overall gas gain.
