According to foreign media New Atlas, we all know that correct sitting posture is very important for health, and sedentary will bring some negative effects. With this in mind, researchers at the Fraunhofer Institute for Silicate Research in Germany have developed an LED seat that can provide guidance for people sitting in their seats. The LED seat is equipped with a plurality of pressure sensors, each sandwiched between two electrode layers made of conductive silicone. By measuring the user's weight distribution, these sensors are able to determine whether a person's sitting posture is ergonomic - more specifically, it can detect whether the user is sitting at an improper angle or staying in a position for too long. The user can then view the video explaining the problem and suggestions on how to correct the problem through the app. The app also guides the user through exercises designed to alleviate problems caused by improper posture and detects if they are practicing correctly through sensors.
A high-speed slip ring is an electromechanical device that allows electrical current to pass between a stationary and a rotating assembly. It is typically used in applications where the speed requirement exceeds that which is achievable with a standard slip ring. High-speed slip rings are available in a variety of sizes and configurations to meet the needs of most applications. They are commonly used in military, aerospace, and medical applications where speed and reliability are critical.
The speed is required to be at least tens of thousands of revolutions per minute, the structure of the Conductive Slip Ring directly determines the contact of high speed, as well as the size of impedance. High-speed slip ring materials have high wear resistance, high life characteristics, and multi-contact contact can ensure signal transmission and power reliability, with the development of science and technology, high-speed slip rings will be more and more widely used.
If you need to transfer large amounts of data or power between two stationary objects, a high-speed conductive slip ring is what you need. Traditional slip rings only offer a few thousand revolutions per minute (RPM), which is more than enough for most applications, but can be limiting in some circumstances. Some applications, like those found in the medical or military field, require speeds of tens of thousands of RPM in order to function properly. That's where our high-speed conductive slip ring comes in. With speeds up to a certain range, it can handle even the most demanding applications.

The data is transmitted wirelessly to a computer or mobile device, processed by a companion application, and then transmitted back to the seat. It responds by illuminating LEDs of certain colors, letting the user know what changes they need to make. 
The researchers are currently demonstrating the system on the MS Wissenschaft exhibition boat in Germany. Researchers believe that this technology can also be integrated into more practical applications such as floor mats or office chairs.
