Researchers at the University of Tokyo in Japan and the University of Texas at Dallas have developed an "ultra-thin thermometer" that can be manufactured using a printing process. The research results are published in the Proceedings of the National Academy of Sciences (PNAS). In the electronic version.
The thermometer is very soft and can be applied to the skin like a band-aid. Simply attach or wrap it around the object to be tested to monitor small fluctuations in temperature.
This material is synthesized with a semi-crystalline acrylate polymer composite and graphite, and its electrical resistance increases with increasing temperature. This positive correlation is called "Positive Temperature Coefficient". coefficient)".
In the synthesis of the polymer, a method of changing the mixing ratio of the two monomers is employed so that the response temperature can be adjusted around the body temperature. Specifically, by changing the ratio of the octadecyl acrylate and butyl acrylate in the polymer, the monitoring interval can be adjusted between 25 and 50 ° C. Therefore, it is very suitable as a temperature sensor for measuring body temperature. The original method of adjusting the response temperature of the polymer PTC is to change the molecular weight, so the controllability of the response temperature is low.
The thermometer is very thin, only 15μm, which is equivalent to 1/4 of human hair; the bending radius is 700μm, as previously mentioned, it can be attached to the surface of a living body, like a band-aid.
It has super high sensitivity (20mk [K is Kelvin, mk is one thousandth of Kelvin]) and response speed (less than 100ms). The higher the sensitivity, the higher the accuracy. For example, a thermometer with low sensitivity can change when it changes by 1 °C, but the high sensitivity of 20mk of this material means that at 25 degrees Celsius, the temperature can be detected by 0.02 degrees. Is it a very goose girl! The response speed below 100ms means that if the temperature changes, the resistance of the temperature sensor will change within 100ms.
The measurable temperature range of the thermometer is 25~50°C, which perfectly covers the human body temperature range (34.7°C~38°C). The team also produced a 12-point x 12-point multipoint thermometer that integrates the active matrix of organic transistors using a printing process. The surface temperature distribution was measured in real time. It accurately measures the temperature stability of the lungs of warm-blooded animals, including the difference between the core temperature of the lungs and the temperature of the inhaled air.
The team attached the temperature sensor developed this time to the lung surface of the mouse and measured the temperature changes accompanying the breathing movement. It was found that although the outside temperature (25 ° C) and body temperature (37 ° C) were very different, the temperature difference between the lungs of the rats during exhalation and inhalation was only about 0.1 °C. Experiments have shown that warm-blooded animals can accurately maintain a constant body temperature.
The intended use of the flexible thermometer is to monitor the body temperature of the baby, to detect abnormalities at an early stage; to monitor the fever caused by inflammation in the affected area; and to measure the body temperature inside the clothes in motion to develop functional sportswear and the like. During the test, the number of consecutive uses of the thermometer reached nearly 2,000. In the future, the research team will further reduce the thickness, increase the number of times that can be repeatedly measured, and strive to achieve commercialization within three years.
As the first university in Asia, Dongda has done a lot of research on flexible materials, such as solar armbands, transparent plastic organic films with sensors, and smart diapers.
As the first university in Asia, Dongda has done a lot of research on flexible materials, such as solar armbands, transparent plastic organic films with sensors, and smart diapers.
The solar arm ring is composed of a flexible amorphous silicon solar panel, a piezoelectric speaker, a body temperature sensor and a power supply short circuit. All parts are made of organic material and can be in direct contact with the skin. This armband can be used to monitor patient signs. A warning can also be issued when the patient's temperature is too high.
The organic film has a thickness of only 2 μm and is very flexible, bendable, stretchable, and foldable. Even if it is placed in a humid environment, it will not affect its performance. It can completely adhere to any part of the body, and the wearer can hardly feel it. Even if the monitoring object is constantly moving, the sensor will not be displaced, detached and damaged, and the vital signs information can be stably monitored. Verification experiments show that the sensor can accurately measure physical quantities (strain) and physiological electrical signals (ECG). 
The smart diaper passes the sensor to detect whether the baby is urinating or not, and then sends the information to the guardian in time through wireless communication. Traditional diapers require the guardian to constantly check if the child is peeing or crying. If it is an electronic sensor, this trouble is saved. This technology can integrate the sensing lines on the film, and each price is only a few yen, and the world feels better.
All of the above studies were conducted by Professor Takao Someya and his team. Professor Takao has been developing organic devices with flexibility and large area. The goal that the professor is aiming at is not just for the surface of the human body, he said that organic devices will also be used in implantable devices.

Feline Infectious Peritonitis (FIP), referred to as Feline Infectious Peritonitis (FIP), is a fatal abnormal immune response that occurs in cats. It is caused by the mutation of the feline coronavirus carried by cats. As a high-incidence and fatal disease of pet cats, the current incidence of feline abdominal transmission is about 10%.
The symptoms of cats are usually divided into two categories, namely wet FIP and dry FIP, of which wet FIP accounts for the majority of all cases. About 70%, manifested as abdominal pleural effusion, abnormal bulging; dry FIP cats have different symptoms, depending on the type of organ affected by the virus.
So far, all feline feline feline treatments are based on the characteristics of the disease, and GS-441524 can play a role in the treatment of feline feline disease. Therefore, the therapeutic effect of GS-441524 is obviously more ideal, the dose used is less, the treatment cycle is shorter, and the efficacy, safety and convenience of operation are all good. Because of this, GS-441524 is considered by many pet owners and veterinarians to be a magic medicine that can effectively treat feline abdominal infection.
