“…Despite of the recent development in biodegradable pressure sensors, there are still some issues, such as sensitivity, operating range, and controllability of biodegradability, essentially to be improved for accurate pressure monitoring of various tissues and organs. In other words, regarding there are huge recent demands for healthcare and diagnosis of diseases in early stage through the pressure sensing of diverse tissues and organs, such as intracranial pressure [ 152 , 153 , 154 , 155 , 156 , 157 ], intraocular pressure [ 158 , 159 , 160 , 161 , 162 , 163 ], heartbeat [ 164 , 165 , 166 ], and bladder pressure [ 167 , 168 , 169 , 170 ], we expect that the high-performance biodegradable pressure sensors will be much more important for diverse biomedical applications in the future.…”

The interest in biodegradable pressure sensors in the biomedical field is growing because of their temporary existence in wearable and implantable applications without any biocompatibility issues. In contrast to the limited sensing performance and biocompatibility of initially developed biodegradable pressure sensors, device performances and functionalities have drastically improved owing to the recent developments in micro-/nano-technologies including device structures and materials. Thus, there is greater possibility of their use in diagnosis and healthcare applications. This review article summarizes the recent advances in micro-/nano-structured biodegradable pressure sensor devices. In particular, we focus on the considerable improvement in performance and functionality at the device-level that has been achieved by adapting the geometrical design parameters in the micro- and nano-meter range. First, the material choices and sensing mechanisms available for fabricating micro-/nano-structured biodegradable pressure sensor devices are discussed. Then, this is followed by a historical development in the biodegradable pressure sensors. In particular, we highlight not only the fabrication methods and performances of the sensor device, but also their biocompatibility. Finally, we intoduce the recent examples of the micro/nano-structured biodegradable pressure sensor for biomedical applications.

Wireless power transfer (WPT) is the transmission of electrical energy to other external/internal devices without the need for wire connection. Such a system is useful to power electrical devices as a promising technology for various emerging applications. The implementation of devices integrated with WPT alters the existing technologies and enhance the theoretical concept for future works. Over the last decade, various studies have been conducted on the applications of magnetically coupled WPT systems, where a general overview over such devices would be beneficial. Hence, this paper presents a comprehensive review over various WPT systems developed for commercially existing applications. The importance of WPT systems was first reported from the engineering point of view, followed by their uses in biomedical devices.

Monitor of intracranial pressure (ICP) system is a life-saving instrument that monitors changes in brain pressure in real time. To implement wireless data transfer, antenna is an indispensable device. In this paper, an implantable antenna is designed with circularly polarized, wideband and compact in size to adapt the application of the ICP monitoring system. First, a one-layer human skin model to verify the basic characteristics of this antenna; and then a multilayered human head model is built to demonstrate the system performance of the designed antenna. In addition, we also considered the human safety to calculate the specific absorption rate value of the proposed antenna. The antenna can transmit different rates over to 1.5 m distance verified by the wireless communication link, which proved it has a good transitions characteristic. Finally, the sample of the antenna is fabricated and tested with help of fresh minced pork. Experiment results shows the antenna with a good property in the ICP monitoring system, as well as other remote medical telemetry system.
