A highly sensitive, wearable gas sensor like an 'electronic nose' for environmental and human health monitoring may soon become commercially available, say researchers. According to the study, published in the Journal of Materials Chemistry A, the sensor device is an improvement on existing wearable sensors because it uses a self-heating mechanism that enhances sensitivity. It allows for quick recovery and reuse of the device. Other devices of this type require an external heater. In addition, other wearable sensors require an expensive and time-consuming lithography process under cleanroom conditions, the study said. "People like to use nanomaterials for sensing because their large surface-to-volume ratio makes them highly sensitive," said study researcher Huanyu Cheng, Assistant Professor at Penn State University in the US. "The problem is the nanomaterial is not something we can easily hook up to with wires to receive the signal, necessitating the need for something called … [Read more...] about ‘Electronic nose’ may soon become commercially available, say researchers
