“…Within conventional hydraulic systems, a key requirement is to monitor and detect debris arising from wear, which can lead to component and system failure. Shi et al [123] divide this into four methods, namely optical detection, acoustic detection, capacitance detection, and inductance detection. The majority of these sensors and sensor systems are not directly integrated into the hydraulic manifold Where sensors are used in hydraulic systems, discussed in detail in Section 3, they are typically placed outside of the hydraulic component to measure specific characteristics of the oil or fluid.…”

Hydraulic fluid power systems are essential for a range of engineering applications such as transportation, heavy industry, and robotics. The scale of the industry is such that hydraulic pumps are estimated to account for 15% of all the energy consumption in the European Union and yet the average efficiency of fluid power systems is only 22%. The digitalization of hydraulic systems offers significant advantages in terms of energy efficiency, performance, reduced maintenance, and automation. However, this requires advances in the integration of smart sensing technologies to provide real‐time feedback on the operation and health of hydraulic components. This review details developing trends in hydraulic fluid power research and provides an overview of progress related to the digitalization of these systems and their integration within an Industry 4.0 framework. The fundamentals of relevant sensor technologies and innovative approaches for integrating sensors into hydraulics systems are discussed. Methods to deliver power to the sensors and associated electronics through harvested pressure ripples are also reviewed. An outlook with respect to future directions in this field is given, including an assessment of the potential for exploiting advanced manufacturing technologies, in particular additive manufacturing, to facilitate successful sensor integration into hydraulic fluid power systems.

“…The simulation inspection showed that the sensor could detect an object with a diameter as small as 10 µm in a 50 × 100 µm cross-section channel, with a capacitance change of up to 0.05 fF. Shi et al [ 95 ] described an integrated sensor consisting of an inductance-resistance sensing unit and a capacitance sensing unit for detecting multi-contaminants in hydraulic oil, as shown in Figure 7 b. Capacitance parameter is used to measure air bubbles and moisture, and the moisture measurement is not interfered by solid impurities. Bubbles of 95 μm were successfully detected in the capacitance experiments, and high sensitivity counting was achieved.…”

Particle counting serves as a pivotal constituent in diverse analytical domains, encompassing a broad spectrum of entities, ranging from blood cells and bacteria to viruses, droplets, bubbles, wear debris, and magnetic beads. Recent epochs have witnessed remarkable progressions in microfluidic chip technology, culminating in the proliferation and maturation of microfluidic chip-based particle counting methodologies. This paper undertakes a taxonomical elucidation of microfluidic chip-based particle counters based on the physical parameters they detect. These particle counters are classified into three categories: optical-based counters, electrical-based particle counters, and other counters. Within each category, subcategories are established to consider structural differences. Each type of counter is described not only in terms of its working principle but also the methods employed to enhance sensitivity and throughput. Additionally, an analysis of future trends related to each counter type is provided.

“…Moreover, they are limited to single-channel detection, which restricts their application in high-throughput analyses. Electrical-based counters, first introduced by Wallace H. Coulter in the mid-20th century, remain popular today. , This technology has evolved into various classifications, including resistance-based, capacitance-based, inductance-based, and impedance-based counters. − ORFLO Technologies has developed a commercial microfluidic impedance-based cell counter Moxi Flow. However, the practical application of these electrical counters is often hindered by their complex design and high costs.…”

With the utilization of advanced microfluidic techniques, the microfluidic particle counter demonstrates significant potential due to its high efficiency, precise manipulation, and portability. This work focuses on a photodetection counter based on optical absorption. To achieve precise particle detection, a Christmas tree-like structure was implemented to separate a single particle from a cluster, which was then detected in independent multiple parallel channels. The system exhibits a high degree of reliability, as evidenced by a linear correlation coefficient over 0.99 obtained during testing with gradient-concentrated beads. Furthermore, when the calculated density of NIH 3T3 cells is compared with that of a traditional flow cytometer, the system achieves a substantial agreement percentage ranging from 87.5 to 99.9%. The system’s ability to perform high-throughput analysis with a high acquisition rate positions it as a promising tool for real-time point-of-care testing.
