Summary:This paper presents a fully printed wireless sensor tag for structural health monitoring of smart lightweight construction parts. The sensor concept aims for sustainability and was developed in line with the European Green Deal, fabricated by inkjet printing on uncoated paper substrate, working without the use of a battery or a chip. Measurement results show a wireless operation over a distance of 3mm, a sensitivity of 4.16 kHz resonant frequency shift per % relative humidity for the humidity sensor, 165 kHz per 1 % strain for the strain sensor and a temperature coefficient of resistance of 1.61*10 -3 K -1 for the temperature sensor. In case of all three sensors, the measurement data shows a linear response and is in good agreement with literature and reference data.
