“…Most ultrasonic power transfer systems bear a resemblance to vibration-based energy-harvesting systems. They use piezoelectric materials for the conversion of ultrasonic signals from a transmitter into electrical energy in a sensor node in a short transfer distance [ 122 , 123 , 124 ]. The CP transfer method utilizes a time-changing electric field between capacitor terminals to transfer power via air.…”

Recently, there has been a growing interest in deploying smart materials as sensing components of structural health monitoring systems. In this arena, piezoelectric materials offer great promise for researchers to rapidly expand their many potential applications. The main goal of this study is to review the state-of-the-art piezoelectric-based sensing techniques that are currently used in the structural health monitoring area. These techniques range from piezoelectric electromechanical impedance and ultrasonic Lamb wave methods to a class of cutting-edge self-powered sensing systems. We present the principle of the piezoelectric effect and the underlying mechanisms used by the piezoelectric sensing methods to detect the structural response. Furthermore, the pros and cons of the current methodologies are discussed. In the end, we envision a role of the piezoelectric-based techniques in developing the next-generation self-monitoring and self-powering health monitoring systems.

Decision-making is an important part of human life and particularly in any engineering process related to a complex product. New sensors and actuators based on MEMS technologies are increasingly complex and quickly evolving into products. New biomedical implanted devices may benefit from system engineering approaches, previously reserved to very large projects, and it is expected that this need will increase in the future. Here, we propose the application of Model Based Systems Engineering (MBSE) to systematize and optimize the trade-off analysis process. The criteria, their utility functions and the weighting factors are applied in a systematic way for the selection of the best alternative. Combining trade-off with MBSE allow us to identify the more suitable technology to be implemented to transfer energy to an implanted biomedical micro device.

“…Wireless power transfer (WPT) techniques have been improved during the development of various applications, such as home appliances, electric vehicles, and unmanned aerial vehicles [1][2][3]. Furthermore, in the biomedical field, WPT plays a growing role in wirelessly energizing implantable biomedical devices (IBMD) [4] and biomedical sensors (BMS) [5]. Different methods have been developed to power these implants and sensors.…”

Implantable biomedical devices (IBMD) and biomedical sensors (BMS) enhance patients’ quality of life by monitoring vital signs, detecting diseases, and replacing malfunctioning organs. However, IBMDs and BMSs require battery power to operate, and they have limited battery life. Wireless power transfer (WPT) is one practical way to address this limitation. In this paper, the authors designed and implemented WPT‐based magnetic resonant coupling (MRC) using a spider‐web coil (SWC) (WPT–MRC–SWC) that supplies the proposed IBMD, including accelerometer sensors, the single‐chip microcontroller ATmega 328, and the nRF24L01 wireless protocol, with power. The WPT–MRC–SWC examines acceleration measurements on three knee‐joint axes (X, Y, and Z) in five different positions: sitting, standing, walking, lying down, and jogging. The SWC of transmitters and receivers (implanted) exhibits an operating frequency of 1.78 MHz with a series/parallel (S/P) configuration. The implanted system's data, transmitted outside the human body using nRF24L01, operates at 2.4 GHz. The results reveal that WPT provides 5 V at an air gap of 60 mm between the receiver and transmitter coils, indicating that it can run or charge IBMD batteries without failure. This study validates the effectiveness of the WPT–MRC–SWC by applying it to an actual application.
