“…For this purpose, strategies like island plus serpentine, filamentary serpentine network, etc [16][17][18][19][20] are implemented with rigid sensors. A variety of elastomeric encapsulated structures like encapsulated wavy ribbon for a pressure sensor encapsulated liquid metal interdigital electrodes for energy harvesting, elastomer-based stretchable strain sensor, mechanically tunable optical transmitter, etc are fabricated, which gives added advantages of flexibility and mechanical protection [21][22][23][24][25][26][27]. Substrate engineering also involves physical/chemical pre-treatment, incorporating special stretchable macro-structures or micro-structures, composite substrate, the introduction of porosity, textile-like weave structures, etc help to obtain a more flexible and stretchable.…”

The substrate plays an important role in flexible devices and sensors. In this direction, it is observed that elastomeric encapsulation assists the sensor system to deform successfully under stretching. The encapsulation not only makes it flexible but also protects it from environmental factors and mechanical damage. In this paper, a Finite Element Method (FEM) analysis is used to study the mechanical effects on the encapsulated system, which provides insight into the design of a stretchable substrate for flexible electronic systems. Here a serpentine silver electrode is designed on a PET (Polyethylene Terephthalate) substrate, which is then encapsulated by PDMS (Polydimethylsiloxane). With the variation in the ratio of top to bottom encapsulation thickness i.e., Ten1: Ten2, the interfacial stress was studied. The mismatch in Ten1 and Ten2 may result in compressive bending strain, which can be avoided by making Ten1 = Ten2. It is observed from the simulation that, there is a spike in von-mises stress at the interface of the substrate and the encapsulation when stretching mode deformation is applied. Also, this maximum stress varies with the variation in encapsulation thickness. For a range of total encapsulation thickness i.e. TEN = Ten1 + Ten2 = 30 µm to 100 µm, the optimum thickness is found to be 55 µm, for which the spike in interfacial von-mises stress is minimum.

“…In recent years, various battery-less and battery-assisted wireless sensing solutions have been developed using NFC and RFID technology in multiple application domains. These applications require the sensing of multiple disparate parameters including temperature, humidity, pH, CO 2 , and pressure [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 ]. Such applications include soil moisture monitoring [ 40 , 41 , 42 ], fruit quality measurement [ 43 , 44 ], long-term building structural health monitoring [ 45 , 46 ], gas monitoring (ammonia, CO 2 and oxygen) [ 47 ], and environmental parameter monitoring [ 48 , 49 ].…”

For the first time, this paper reports a smart museum archive box that features a fully integrated wireless powered temperature and humidity sensor. The smart archive box has been specifically developed for microclimate environmental monitoring of stored museum artifacts in cultural heritage applications. The developed sensor does not require a battery and is wirelessly powered using Near Field Communications (NFC). The proposed solution enables a convenient means for wireless sensing with the operator by simply placing a standard smartphone in close proximity to the cardboard archive box. Wireless sensing capability has the advantage of enabling long-term environmental monitoring of the contents of the archive box without having to move and open the box for reading or battery replacement. This contributes to a sustainable preventive conservation strategy and avoids the risk of exposing the contents to the external environment, which may result in degradation of the stored artifacts. In this work, a low-cost and fully integrated NFC sensor has been successfully developed and demonstrated. The developed sensor is capable of wirelessly measuring temperature and relative humidity with a mean error of 0.37 °C and ±0.35%, respectively. The design has also been optimized for low power operation with a measured peak DC power consumption of 900 μW while yielding a 4.5 cm wireless communication range. The power consumption of the NFC sensor is one of the lowest found in the literature. To the author’s knowledge, the NFC sensor proposed in this paper is the first reporting of a smart archive box that is wirelessly powered and uniquely integrated within a cardboard archive box.

“…So far, a variety of LC passive sensors have been presented for monitoring different parameters such as bacteria strains [23], pH [24], corrosion [25], and so on. Recently, LC resonator-based passive NFC sensors have been demonstrated for use in different Internet of Things (IoT) applications such as a smart medical bandage with temperature and strain sensing [26], a strain sensor for smart packaging [27], and an ammonia sensor for monitoring food spoilage in packages [28]. They use standard NFC readers such as smartphones with NFC.…”

This article presents a flexible printed radiofrequency identification (RFID) sensor based on a printed inductive-capacitive (LC) resonator circuit and a potassium ion-selective electrode (ISE) for remote potassium ion sensing. The potassium ion concentration of the contact solution can be monitored by measuring the change of the resonant frequency of the RFID sensor. The resonant frequency of the sensor can be directly detected by measuring the induced change in the reflection coefficient (S 11 ) of an external interrogator coil that is inductively coupled to the RFID sensor. Results obtained for the RFID sensor exhibited a second-order exponential relationship between the resonant frequency of the sensor and the K + concentration of the solution over 0.001-2 mol/L dynamic range values. Effects of varying separation distance between the sensor and the interrogator coil and the effect of temperature variations on sensor's measurement are shown. With less than 2-s response time and the long-term stability, the wireless passive printed sensor has potential for low-cost K + monitoring applications such as K + monitoring in food packages.
