Modern physics experiments require particle detectors with excellent performance, in particular the spatial resolution of trackers. This usually leads to systems with very high numbers of electronic channels, from 10,000 to several millions. All these channels represent a significant cost of an apparatus, even if in many cases the useful signal is concentrated on a small fraction of them, for a given event. Using the redundancy of the signal, in particular in Micro-Pattern Gaseous Detectors (MPGDs), we have developed a multiplexing technique that can considerably reduce the size of the electronics. A first Micromegas prototype has been tested with 1024 strips readout by 61 channels, showing à 90% efficiency to MIPs. Another prototype built from the resistive technology will be tested in April, to reach efficiency close to 100%. This multiplexing can be easily used in physics experiments to optimize the size of the electronics to the incident flux, and extended to other types of detectors. Furthermore, it offers many new applications beyond particle physics, like in volcanology or archeology. Several industrials also express interest for this technology, in particular for mining exploration.
