In March 2020, the prevention and control of COVID-19 Pandemic has entered a new stage. The response levels of many provinces in China are downgraded, and the prediction model of the Zhong Nanshan Academician team shows that the pandemic may end in June ... All signs show that the COVID-19 Pandemic has been effectively prevented and controlled in China. This protracted "national war against COVID-19 pandemic" has appeared an apparent turnaround. In contrast to the China’s situation, the pandemic in foreign countries is getting worse. As of March 18, the cumulative infections abroad have exceeded 80,000, causing nearly 3,000 deaths. The pandemic in Italy, Iran and other countries are even more severe. As of March 18, the cumulative fatalities worldwide are over 5,000.

Although the main battlefield against pandemic has been transferred from China to foreign countries, the situation of pandemic prevention and control in China is still grim and complex since overseas imported cases have appeared in many Chinese cities. The vigilance against COVID-19 still cannot go down. Many "black-tech" applications have also been put into the "protracted war" of pandemic prevention and control as superb anti-pandemic instruments in a timely manner. Among them, a revolutionary flexible electronic technology exerts its miracle effect and provides a targeted complete solution which can meet the rising demand for continuous temperature monitoring under pandemic prevention and control.


Why is temperature monitoring a key difficulty in pandemic prevention and control?

In the prevention and control of this pandemic, the Chinese government has adopted positive response measures like crowd quarantine, temperature monitoring and other control measures. Among them, the temperature detection has become the first step to filter the potential COVID-19 infections. In public places, traffic crossings, home quarantine, etc., the primary confirmation methods adopted are temperature. Crowded places such as stations, supermarkets, hospitals and other public places are logically the key areas for pandemic prevention and control.


△ Crew members and doctors measure temperature of passengers on the plane


However, common temperature-measuring devices (infrared thermometers, mercury thermometers, etc.) have different degrees of "deficiencies". For example, traditional temperature measuring devices cannot automatically record temperature data and are easily affected by ambient temperature; some temperature-measuring devices have high user experience requirements, people must be trained to use it and they cannot be used "plug and play". Direct-contacting temperature measurement is prone to cross infection, so it is not suitable to use such temperature measuring devices that directly contacts the human body like mercury thermometers. In stations, supermarkets etc. which always have a large flow of people, traditional temperature measurement cannot accurately locate personnel, some body temperature measuring devices are too large in weight and volume to carry around. These problems have also become difficult and pain points for the target group's temperature monitoring.

Take the aircraft cabin -- a closed environment as an example to show the use of smart wearable temperature tag in the following flowchart:


△ Temperature throughout monitoring for people overseas entering China


During present COVID-19 pandemic, a flight takes a temperature measurement every half an hour and a complete historical temperature file is established before disembarking and handed over to the local management agency at the destination. Zhong Nanshan, a high-level expert group leader of the National Hygiene and Health Commission and an academician of the Chinese Academy of Engineering, said that many provinces and cities in China have maintained zero growth in new cases of COVID-19 now, indicating that this pandemic has been controlled to a certain extent. In this context, wearable temperature measuring stickers are believed to be able to better help relevant departments to take anti-virus preventive and control measures.

Take the use in a hospital quarantine ward as an example in flowchart below:

Also, as a place of control, such as home quarantine, hospital quarantine and office personnel management, there are different requirements of continuous body temperature measurement, especially for mass people temperature measurement. There are many problems such as huge numbers of people to monitor, complex temperature measurement, and difficultly to record temperature continuously. The introduction of wearable temperature tag can realize real-time monitoring of target person and observation of body temperature data. It can also identify and exclude potential threats through long-term monitoring, helping administrative departments and agencies to achieve personnel management monitoring.

Following the Huoshenshan Hospital and the Leishenshan Hospital, the "mobile cabin hospital" played a huge role in the public health emergency protection of the COVID-19 pandemic in China. On March 10, 2020, as the last batch of 49 patients stepped out of the Hongshan Gymnasium, the first mobile cabin hospital in Wuhan, which operated for 35 days, was officially closed. Enfucell intelligent wearable temperature tag with "flexible electronics" as the core technology has been applied in Wuhan’s mobile cabin hospitals, which successfully solved the problem of continuous temperature detection of patients and fully demonstrated continuous temperature measurement, accurate data and long-term continuous recording and other features, which have won unanimous praise from the hospital and patients.

Iontophoresis Face Mask

△ Enfucell Iontophoresis Face Mask

The Iontophoresis face mask consists of a conductive non-woven mask and a pair of 1.5V SoftBatteries (called Iontophoresis battery patch). The battery enables the Iontophoresis process. Iontophoresis is defined as the introduction, by means of a direct electrical current, of ions of soluble salts into the tissues of the body for therapeutic purposes. It is a technique to enhance the transport of drug ions across tissue barriers, such as the skin. When the Enfucell Iontophoresis Face Mask is in use, the anode electrode of battery is on the serum saturated mask, and the cathode electrode is on clean skin. A complete current circuit is formed through the skin and the iontophoresis process starts. Water in the cosmetic flows from the active electrode to the skin, any active aqueous solution, ionic or non-ionic, enters the skin with water.

Compared to traditional masks, the mask integrated with a SoftBattery has a quicker effect. And thanks to the thin and flexible printed battery, Iontophoresis masks are more convenient to use than conventional iontophoresis devices which are bulky and non-disposable. The Enfucell Iontophoresis Face Mask makes beauty care more effective and more convenient.
