Due to the necessary transition to renewable energy, the transport of electricity over long distances will become increasingly important, since the sites of sustainable electricity generation, such as wind or solar power parks, and the place of consumption can be very far apart. Currently, electricity is mainly transported via overhead AC lines. However, studies have shown that for long distances, transport via DC offers decisive advantages. To make optimal use of the existing route infrastructure, simultaneous AC and DC, or hybrid transmission, should be employed. The resulting electric field strengths must not exceed legally prescribed thresholds to avoid potentially harmful effects on humans and the environment. However, accurate quantification of the resulting electric fields is a major challenge in this context, as they can be easily distorted (e.g., by the measurement equipment itself). Nonetheless knowledge of the undisturbed field strengths from DC up to several multiples of the fundamental frequency of the power-grid (up to 1\,kHz) is required to ensure compliance with the thresholds. Both AC and DC electric fields can result in the generation of corona ions in the vicinity of the line. In the case of pure AC fields, the corona ions generated typically recombine in the immediate vicinity of the line and, therefore, have no influence on the field measurement further away. Unfortunately, this assumption does not hold for DC fields and hybrid fields, where corona ions can be transported far away from the line (e.g., by wind), and potentially interact with the measurement equipment yielding incorrect measurement results. This review will provide a comprehensive overview of the current state-of-the-art technologies and methods which have been developed to address the problems of measuring the electric field near hybrid power lines.

“…One limitation that has plagued lab-on-a-chip devices has been the lack of a miniaturized sensor that facilitates the development of high-sensitivity assays. Several technologies have been explored including Mass spectrometry field [4,5], electrochemical sensors field [6], optical detection field [7,8], surface plasmon resonance spectroscopy field [9], and interferometry [10,11] but each has significant limitations in complex biological matrices. The SAW biosensor technology is based on Surface acoustic waves (SAW), a type of acoustic wave that propagates along a surface of a solid material [12][13][14].…”

There has been a renewed interest in the development of surface acoustic wave (SAW) biosensors because they hold great promise for opening new frontiers in biology and medicine. The promise of SAW technology is grounded in the advantages SAW devices hold over traditional laboratory techniques used in biological and medical laboratories. These advantages include having smaller sizes to allow greater portability, using smaller sample volumes, requiring lower power requirements, the ability to integrate them into microfluidic platforms, and their compatibility with smart devices such as smartphones. The devices offer high sensitivity and can be designed to allow microfluidic interfacing. Other major advantages of SAW-based technologies include the fact that they can be operated remotely in harsh conditions without the need for an AC power supply. Their compatibility with lab-on-a-chip systems allows the creation of fully integrated devices with the ability to isolate the sample from the operator. In this mini-review, we will discuss SAW devices and their ability to enable a variety of applications in Biology and Medicine. The operating principles of the SAW biosensors will be discussed along with some technological trends and developments.

This paper proposed and experimentally demonstrated a high-resolution voltage measurement method based on fiber loop cavity ring-down (FLCRD) technology and polymer dispersed liquid crystal (PDLC) film as the sensing device. In this measurement system, PDLC is made into a film structure used as sensing device to measure external voltage changes, and the experiments were carried out to measure the relationships between light transmittivity of PDLC film and the external voltage. The FLCRD system with optimized structure parameters is obtained by numerical simulation, and the splitting ratios of fiber couplers used in the sensing system are optimized, and an erbium-doped fiber amplifier is used to compensate system signal loss, which has made a lot of improvement in the signal noise ratio and sensitivity. Finally, the experimental results show that the resolution of voltage measurement is 0.29 mV (0.0015%) in the range of 0-60V, which improved the resolution by 10 times compared with the current methods.
