Researchers are continuing to align new technology and increased medical understanding to provide even more ways to help diabetics live healthier lives. Antenna sensors are also being developed for non-invasive glucose monitoring. Wearable technology in healthcare has several advantages, including convenience, lower healthcare costs, improved diagnosis, and improved patient outcomes. A wearable patch antenna can be a passive sensor to detect various body signals. Signal acquisition and linear regression modeling monitor fluctuating diabetes levels with an antenna sensor. The antenna's operating frequency is set to 4.1 GHz, which is in the industrial, scientific, and medical (ISM) frequency band. As a substrate material, rigid FR4 (r = 3.5, tan = 0.0027, and thickness of 0.1 mm) is used. The proposed antenna will improve return loss, VSWR, gain, and efficiency. In comparison to other existing wearable antennas, it has a lower return loss, VSWR, gain, and specific absorption rate (SAR). The achieved antenna return loss at 4.1 GHz is approximately 37 dB, the achieved directivity at 4.1 GHz is 2.1 dBi and the achieved gain is 1.8 dBi. The VSWR value obtained at 4.1 GHz is acceptable in terms of impedance matching. The proposed antenna design is designed and simulated using CST. The acquired signal from the thumb tip antenna was processed using the linear regression algorithm to calculate the blood glucose level. The experimental results indicate that, with regression modeling, the signal from the thumb tip antenna could be used to more reliably monitor blood glucose levels than existing invasive methods. The experimental results validated blood glucose levels taken from the thumb tip using an AccuChek glucometer.

In this paper, a noninvasive bone fracture monitoring system is developed using a planar monopole antenna. The proposed antenna provides an ultra-wideband response, and its overall size is 18 × 19 × 0.8 mm3. The proposed ultra-wideband monopole (UWM) antenna has a maximum measured gain of 3.77 dBi, and the maximum SAR value for an input power of 18 dBm is less than 1.6 (W/kg) (1 g). A bovine tibia is experimentally tested using a proposed UWM antenna to monitor the fracture recovery process and then further analysed using principle component and linear regression analysis. In addition, a microcontroller with a wireless communication module is developed to monitor the data in an Android application. The proposed system could be a promising approach for developing a portable, noninvasive monitoring device.

This article proposes a flexible ultra-wideband (UWB) antenna for wearable electronics and biomedical applications. The antenna presented for this work is fabricated on a Kapton polyimide (PI) substrate, and the operating frequency ranges from 2.4 GHz to 7.1 GHz. The footprint of the proposed antenna is 35 × 45 mm with an elliptical radiating element fed by coplanar waveguide (CPW), which achieves improved impedance matching characteristics. The choice of substrate, design constraints, fabrication process, and bending test of the proposed flexible UWB antenna are explained in detail in this paper. A comparative study on the choice of substrate is performed and the Kapton PI is chosen as the substrate material, which makes the antenna less susceptible to degradation in antenna performance that arises due to bending effects. The measurement and simulated results of the fabricated antenna show a good degree of agreement. The return loss performance of the proposed antenna is greater than -10 dB in all the operating bands with improved gain and directivity. The flexible nature with multiple frequency bands of operation and good bending performance makes the proposed antenna appropriate for wearable electronic and biomedical applications.
