Coffee robots that can pull flowers have emerged in Chongqing to lead into the intelligent era.

If you take a breath, you will know if you have lung cancer. At the high-tech fair, the research team of Chongqing University brought this machine.

"some volatile organic gases in the exhaled air of the human body are closely related to whether the human body has lung cancer or even the degree of lung cancer, and it can be used as a marker for the diagnosis of lung cancer." "there are mainly nine organic gases," researcher Yi Xin told reporters. "

Yi Xin said that the key to this technology lies in sensitive materials, and only good sensitive materials can accurately identify and send signals. At present, the research group has developed a porphyrin biochemical sensor chip. "loaded in the lung cancer diagnostic instrument, this chip is only inch-sized, and there are 36 different color dots on the surface, each of which is made of special chemical substances. When the collected breath enters the interior of the instrument, there will be a chemical reaction with these dots."

It is understood that the lung cancer diagnostic instrument research team will next jointly carry out clinical trials with the Department of Respiratory Medicine of Xinqiao Hospital of the third military Medical University, and it is possible to determine the severity of lung cancer patients through detection and analysis in the future.

After passing the clinical trial, the lung cancer diagnostic instrument is expected to be used for routine physical examination, whether suffering from lung cancer can be screened and known in the early stage, thus greatly improving the survival rate of patients with lung cancer.

A hydrogen fuel cell car costs only 20 yuan to drive 300 kilometers.

A kind of hydrogen fuel cell which can generate electricity continuously without charging and only needs hydrogenated energy or hydrogenated fuel water has attracted much attention. According to the staff, this kind of battery can be used in family cars, mountain bikes, motorcycles and other models.

"traditional electric cars need to be recharged, but hydrogen fuel cell vehicles only need to buy hydrogen fuel water in convenience stores, gas stations and other places in the future." The staff member calculated that the hydrogen fuel cell car would cost only 20 yuan to drive 300 kilometers.

According to reports, in November last year, the hydrogen energy project of Boyan New Energy Investment Company was launched in Chongqing, applying hydrogen energy to vehicles, taking hydrogen power stations as the core, using crop straws, agricultural waste and kitchen waste to produce hydrogen for power generation, to build several comprehensive demonstration bases for recuperation for the elderly, three-dimensional farms, tourism, and hydrogen power stations.

This robot can make 20 kinds of coffee and pull flowers.

In the future, the coffee you drink may be made by a robot. At the booth in Yongchuan District, a robot named "coffee" specializes in making coffee. "it can make twenty kinds of coffee, including lattes." "not only that, but if we set the program, it can also pull flowers," Mr. Liao, a developer, told reporters. " After making the coffee, the "coffee" will also send the coffee to you.
