![]() The vibrations can originate from heavy mining machines such as scrapers, dozers, haul truck, shovels, loaders, load haul dump vehicles, shuttle cars, and most of the earthmoving equipment. ![]() For instance, whole body vibration (WBV) in mining sites has been recognized as one of the major industrial hazards in many mining operations. Vibration exposure can cause a range of health problems, including lower back pain, neck pain, headaches, and gastrointestinal track problems. ISO standard (ISO 2631.1) considers vibration exposures in the frequency range between 0.5 and 80 Hz as harmful to human health. ] Vibration sources are available everywhere from body movement and dynamic motions of industrial machineries, bridges, buildings, vehicles, household appliances, etc. Mechanical vibrations, compared with other ambient energy sources available in the environment, contain higher power density that sustains self‐powered sensors. A popular form of mechanical energy is vibration energy which is available in variety of forms and scales around people's daily life. ] One of these energy sources is environmental vibration. Therefore, wide range of researches are concerned to design and build novel power sources that can convert mechanical into electrical energy to sustain power for smart electronic devices and provide operation durability. ![]() Powering smart devices with batteries has some challenges including: i) short service life, ii) recycling issue and consequent environmental impact, iii) fires and explosion risk, iv) large size batteries are not desire for small electronic devices. ] The sensors need an accessible and sustainable power source and batteries frequently do not provide the requirement of desirable longevity, thus requiring regular maintenance and therefore ongoing expenses will rise. Sensors are critical devices for remote monitoring of human, structures, and environment. Lastly, the challenges and perspectives are discussed for reference to the researchers who are interested in self‐powered vibration sensors.ĭevelopment and widespread application of internet of things (IoT) technology in sensors over the past decade, provide opportunity for processing and online monitoring to be deployed in our daily life. ![]() The recent progress in self‐powered vibration sensors and systems from the perspective of the underlying materials, applications, and fabrication techniques is reviewed. This review can critically analyze the vibration effect on workers’ health, the limitations of currently available devices, explore new options for powering different personal protective equipment devices, and discuss opportunities and directions for future research. Repetitive vibration exposure is one such hazard, e.g., whole body vibration, yet it can also provide parasitic energy that can be harvested to power wearable sensors and overcome the battery limitations. While wearable sensors technology can aid in early detection and long‐term exposure tracking, powering them and the associated risks are often an impediment for their widespread use, such as the need for frequent charging and battery safety. Workers are often exposed to harmful conditions-especially in the mining and construction industries-where chronic health issues can emerge over time. ![]() Recent advances in wearable energy harvesting technology as solutions to occupational health and safety programs are presented. ![]()
