- Abstract:
- Although the response mechanism of carbon nanotubes (CNTs) based sensors exposed to a variety of gases has been extensively discussed and studied, pristine onion-like carbon (OLCs), part from the same class of fullerenes, have not been fully investigated as sensing application. A room-temperature working chemiresistor based on onion-like carbons (OLCs) as sensing element with good sensitivity has been developed and tested with the main purpose of being implemented within the next generation of gas sensors. Many industries require a room temperature working gas sensor without an external heating source: leakage detections of explosive gases (such as hydrogen), detection of flammable gases and explosives in plants, biomedicine and pharmaceutics, monitor combustibles, early detection of fires, realtime detections of toxic or pathogenic gases in industries, ambient environmental monitoring and control. One industry that would also benefit from development of such a sensor is the food industry which requires a smart label that warns the consumer on the presence of toxic substances to avoid ingestion of contaminated food. Ingestion of food contaminated with different chemicals due to a malfunctioned manufacturing process or due to food spoilage from an improper storage could trigger severe trauma within human body.
