“…A wireless LC sensor has a capacitor (C) in resonance with an inductor (L), and the resonant frequency changes with external effects, and it can work wirelessly without the need for a battery or any kind of power source [7]. Inductor-capacitor (LC) sensors have been widely used for the wireless detection of changes in pressure [8], temperature [9], humidity [10] and chemicals [11]. Continuous wireless monitoring without the need for a power supply, cost-effectiveness, and long service life are the main advantages of wireless LC sensors [12].…”

The development of wireless sensing technologies paves the way for advances in the fields of wearable devices, prosthetics, and robotics. Wireless communication between sensors and readers plays an important role in recent internet of things (IoT) technologies. Among many types of wireless sensing devices, wireless passive radio frequency (RF) devices including LC (inductor-capacitor) resonators have been spotlighted. However, passive LC sensors suffer from short-range wireless detection, and their fabrication process requires several processes. Here, we designed a 3D integrated wireless compact LC location sensor fabricated by the 3D printing method for the multi-layered devices. The fabricated wireless sensing system shows the increased wireless reading distance up to ten centimeters. Also, a dielectric material with high dielectric permittivity has been applied to enhance the quality factor of the sensors by 2.5 times with improved wireless detection.

With the development of wireless technology and flexible electronics, flexible frequency reconfigurable antennas have been directly used as sensors to detect mechanical signals. As an important frequency reconfigurable antenna, microstrip antenna has been widely studied in the field of flexible and flexible electronics in recent years. However, the stretchability of microstrip antennas usually comes at the cost of reducing the conductivity of the radiated conductor. Here, we report a flexible force sensitive frequency reconfigurable microstrip antenna, which fabricated by silver fiber conductive fabric with a double-wire braided structure. In order to increase the detection of pressure, an elastic dielectric layer with a microhemispheric array was introduced into the microstrip antenna to extend the frequency band width of the reconfigurable antenna. The relative frequency of the antenna varied from 0~-12.9%, and the sensing sensitivity was -1.9 kPa-1. As potential applications, we demonstrate the use of a flexible frequency reconfigurable antenna base on stretchable conductive fabric as a strain sensor capable of measuring bending angle and movements of a human finger. The change in the resonance frequency with the externally applied tensile strain in this antenna design has a sensitivity of 3.448, manifesting a 4.19- and a 13.79-fold increase of sensitivity when compared to those in previous reports that used arched or both-planes serpentine rectangular microstrip antenna. This is of great significance for the application of wearable antenna in wireless mechanical sensing technology.

“…To identify resonant frequency changes, the S 11 parameter is measured. While a patch antenna has been used as a wireless sensor node in previous research, the proposed patch sensor operates at a greater sensing distance compared to other reports in the existing literature [ 4 , 5 , 6 , 7 ].…”

This paper presents a design for temperature and pressure wireless sensors made of polymer-derived ceramics for extreme environment applications. The wireless sensors were designed and fabricated with conductive carbon paste on an 18.24 mm diameter with 2.4 mm thickness polymer-derived ceramic silicon carbon nitride (PDC-SiCN) disk substrate for the temperature sensor and an 18 × 18 × 2.6 mm silicon carbide ceramic substrate for the pressure sensor. In the experiment, a horn antenna interrogated the patch antenna sensor on a standard muffle furnace and a Shimadzu AGS-J universal test machine (UTM) at a wireless sensing distance of 0.5 m. The monotonic relationship between the dielectric constant of the ceramic substrate and ambient temperature is the fundamental principle for wireless temperature sensing. The temperature measurement has been demonstrated from 600 °C to 900 °C. The result closely matches the thermocouple measurement with a mean absolute difference of 2.63 °C. For the pressure sensor, the patch antenna was designed to resonate at 4.7 GHz at the no-loading case. The sensing mechanism is based on the piezo-dielectric property of the silicon carbon nitride. The developed temperature/pressure sensing system provides a feasible solution for wireless measurement for extreme environment applications.
