According to foreign media TechRadar, researchers from the Federal Institute for Polytechnics in Lausanne (EPFL) in Switzerland have successfully developed a circuit system that can bend and stretch, stretching to four times the original size.

Nowadays, rigid circuit systems are used in electronic devices, and the newly developed flexible circuit systems are more ergonomic. They can be shaped into what consumers want, and therefore wearable devices, skin biosensors and smart clothing, etc. The application prospects are very optimistic.

It is understood that this flexible circuit system uses a flexible polymer and a liquid metal in combination. Researchers even think that it can withstand more than one million stretches and folds without losing its proper function.

Stéphanie Lacour, a researcher from the EPFL biological laboratory, said that the current size of the flexible circuit system is relatively large, but they can quickly reduce the size of the system. She said: "We use our own development of deposition and construction methods that can reduce the thickness of the system without affecting its reliability." Once this technology is put into use, it means that the wearable device will become more comfortable and life More lasting.

Pull Out Faucets

The present invention provides a multifunctional pull faucet, comprising: a faucet body, a drawing part is provided at the water outlet port thereof, and the drawing part is connected to a main channel, wherein at least three are provided in the faucet body A branch channel, and the three branch channels are all connected to the main channel. A multifunctional pull faucet provided by the present invention, wherein the hot water channel, the cold water channel and the water purification channel (pure water channel) are all connected to the main channel , And the main channel is connected with the drawing part on the main body of the faucet, so that the drawing part can obtain the water quality (hot water, cold water, purified water or pure water) required by different users, thereby improving the user experience, and , By integrating the hot water channel, cold water channel and pure water channel (pure water channel) into the main channel, the internal structure of the faucet is simplified, and the production cost of the faucet is reduced.
