“…[72] Piezoelectric materials, especially piezo polymers such as PVDF, offer good possibility to be used in PPE as wearable vibration sensor. These materials can detect environmental vibration and also any pressure or deformation that comes from human biomechanical activities [77][78][79] including breathing, [80,81] blinking, finger movement, and gait, [82] which made them suitable candidate for health monitoring of mine workers through smart PPE. PPE as the sensor plays a significant role in fulfilling the requirement of safety in a range of environmental sensing, monitoring, and risk identification for mine workers.…”

Recent advances in wearable energy harvesting technology as solutions to occupational health and safety programs are presented. Workers are often exposed to harmful conditions-especially in the mining and construction industries-where chronic health issues can emerge over time. 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. 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. 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. The recent progress in self-powered vibration sensors and systems from the perspective of the underlying materials, applications, and fabrication techniques is reviewed. Lastly, the challenges and perspectives are discussed for reference to the researchers who are interested in self-powered vibration sensors.

“…In a wide moisture range from 0 to 97.5% RH, high sensitivity (3.6 k/% RH), low hysteresis (3% RH), and good repeatability were attained. An eco-friendly cotton fiber-based piezoresistive textile (CF ptextile) for biomonitoring was created by Pan et al 27 MXene flakes were applied using a dip-coating technique to the porous cotton cellulose fibers, resulting in a solid bond thanks to hydrogen bonding. In recent years, metal oxide semiconductors have been widely used as gas sensors for the detection of toxic and flammable gases.…”

A gas sensor is a device that detects the presence of gases in a specific area. This research work demonstrates the effectiveness of gas sensors based on graphene oxide (GO) and copper oxide (CuO) semiconductor nanomaterials for the detection of carbon dioxide. GO and CuO were prepared by the modified Hummer’s method and precipitation method using CuCl 2 as a precursor, respectively. These materials are made into a hybrid using poly(vinyl alcohol) (PVA)/poly(vinylpyrrolidone) (PVP) polymer solutions of low concentrations and are spin coated onto the pattern-etched copper-clad substrate. The sensor is tested using a source measurement unit (SMU) to obtain the change in the resistance of the sensor in open air and in a carbon dioxide environment. The fabricated sensor with an Arduino microcontroller detection unit showed a good sensing response of 60%.
