One of the most widely recognized pressure relief devices is the specialized mattress or mattress overlay. These products are designed to redistribute body weight and reduce pressure points, significantly lowering the risk of developing bedsores. Advanced options include alternating pressure mattresses, which use air cells that inflate and deflate cyclically to enhance circulation and relieve pressure. These innovative solutions are essential in hospitals and long-term care facilities where patients spend substantial amounts of time in bed.

Compressed Natural Gas (CNG) is increasingly gaining attention as a cleaner and more sustainable alternative to traditional fossil fuels. As the world grapples with the impacts of climate change and air pollution, the transition to greener energy sources has become imperative. CNG, primarily composed of methane, is a fossil fuel that has been compressed to a pressure at which it occupies a smaller volume, making it easier to store and transport.

Another widely used method involves electrochemical sensors, particularly for detecting toxic gases like carbon monoxide (CO). These sensors consist of electrodes immersed in an electrolyte solution. When a target gas interacts with the electrodes, a chemical reaction occurs, generating an electrical current that is proportional to the gas concentration. This method is advantageous for portable applications, such as personal gas detectors.
