Piante all'apparenza sane che cadono, rischiando di ferire o uccidere ignari passanti: uno strumento sviluppato dalla SUPSI in collaborazione con l'Università di Genova e partner industriali italiani e ticinesi potrebbe permettere di radiografare lo stato di salute degli alberi senza procedere ad abbattimenti preventivi.
Il progetto si chiamata MATHEW (Microwave Axial Tomograph for the Health Examination of Wood) e consiste in un sistema elettronico a microonde per l'analisi tomografica del legno. Il prototipo realizzato è portatile ed applicabile a tronchi di diverse dimensioni, di cui fornisce immagini bidimensionali dell'interno. In questo modo, è possibile individuare zone marce.
