A cheap printed sensor could transmit wildfire warnings. Wildfires have recently destroyed regions across the world, and their gravity is increasing. Hoping to reduce harm, researchers led by Yapei Wang, a Chinese chemist of Renmin University, say they have developed an inexpensive sensor to detect such fires earlier with less effort.
The team says its new sensor can be placed near tree trunks' bases and send a wireless signal to a nearby receiver if there is a dramatic temperature increase. That heat also powers the sensor itself, without replacing batteries. The team printed the substances onto ordinary paper to create a sensor for just $ 0.40.

Current detection methods rely heavily on human watchfulness, which can delay an effective response. Most wildfires are reported by the general public, and other alerts come from routine foot patrols and watchtower observers. Passing planes and satellites also occasionally spot something, but "the fire first appears on the ground," Wang says. "When you see the fire from the sky, it is too late."

watch for fires in California, Nevada and Oregon. "The whole way that you respond to a fire until it's put out is like a ballet," he says. "You'd have to choreograph(设计)it just so, with resources precisely used at
But improving coordination among the different agencies involved in firefighting is even more crucial
to address, says Graham Kent, an earthquake expert at the University of Nevada, Reno, who was not part
the right time and place and in the right order from detection to confirmation to assignment to extinguishment(熄灭). Fire detection is just step one."
Wang says his team's next steps are to extend the device's signal range beyond the current 100 meters,
