Abstract

Abstract: In this article, a sustainable, multifunctional, low‐cost, wireless sensor tag is presented. The sensor tag combines three different environmental sensors in one single platform for the dedicated purpose of wireless structural health monitoring of a variety of applications. However, the adaptive design allows the integration of different sensors depending on the specific sensing task. The material consumption is minimized by double‐sided printing, resulting in compact, resource‐efficient sensor solutions. On one side, the tag is equipped with a printed antenna, a fully passive silicon‐based near‐field communication chip and a carbon‐based strain sensor, while the environmental sensors for humidity and temperature are printed on the other side. Due to its low cost, the usage of environmentally friendly materials and the absence of a battery, the biface sensor tag is a milestone in the field of wireless, sustainable electronics for ubiquitous sensing applications. The fabrication itself comprises a series of processes with a focus on efficient additive manufacturing. The characterization of the three sensors shows sensitivity values and characteristics comparable to those found in literature and industrially manufactured sensors. The utilization of a smartphone for reading out the sensor signals further emphasizes the sustainable approach of this sensor system. Abstract : The article presents the fabrication and characterization of a wireless passive single‐chip multi‐parameter sensor. The paper‐based tag combines three environmental sensor elements, which are fabricated on uncoated paper by means of additive manufacturing. The characterization results show sensitivity values and characteristics comparable to industrially manufactured sensors and those reported in the literature.
