More than 100 years ago, scientists invented a Mobile Camera Receiver to take pictures in any place. More than 30 years ago, engineering scientists invented a Mobile Communica-tion Transceiver to make phone calls in any place. Almost 4 years ago we started to invent a Mobile MAteRIal TranscEiver to explore surface and sub-surface materials in any place.All these groundbreaking inventions relied on important technological advances, enabling us to gradually progress from “bricks” composed of electronic components via integrated circuits towards a complete solution. Following these steps, we aim to extend the benefits of today’s static and bulky material detection systems with a Mobile MAteRIal TranscEiver. This will enable us to achieve sig-nificant breakthroughs in numerous applications with societal relevance: to autonomously localize the source of a fire or unconscious people within a burning building, to reliably detect cables and artefacts inside a wall, or, more generally, to systematically create material maps, e.g. for searching and classifying objects in arbitrary environments. MARIE’s sensing frequency started at 250 GHz and it ends at 5 THz, rendering a variety of materials identifiable as a result of molecule absorption lines. The research challenges of MARIE are fourfold: first, to thoroughly measure, analyze and model the dynamical wave propagation for almost unexplored frequencies; second, to compactly realize wire-less transceivers over such frequency range for mobile material exploration; third, to dynamically characterize surface and also sub-surface materials; and fourth, to precisely localize such materials with sub-mm resolution. MARIE is structured into three phases, each one with a duration of 4 years: the 1st Static Lab phase (2017-2020) which is soon coming to an end successfully, with the demonstra-tion of significant lab-based advances in technology and with frequencies up to 4 THz. Enriched with this know-how, we now embark into the 2nd phase of our ambitious endeavor: A Mobile Sensor (2021-2024), developed in detail in this proposal. The core aim here is to address mobility with an extended frequency range towards 5 THz. In the 3rd phase these concepts will be extended even further into a Dynamic Environment (2025-2028) mainly by fusing with additional sensing principles, to ultimately achieve the vision of a Mobile MAteRIal TranscEiver.
