In a paper published online by the British magazine "Flexible Electronics" on the 13th, Chinese and American scientists introduced a method for manufacturing "electronic tattoo" sensors at low cost. This new metal sensor is only a thousandth of a millimeter thick and can monitor key health parameters such as heart rate and skin temperature. It is applied directly to the skin and is flexible enough to conform to the skin texture without hindering normal sweating or body movement.
“Electronic Tattoo†transmits a variety of body information such as ECG and EMG to the terminal through a tattoo-like sticker. It has great prospects in medical or human-computer interaction and is considered to be the ultimate in wearable devices. Sensor shape. However, at present, the conventional method of manufacturing "electronic tattoo" using inorganic electronic materials is costly and time consuming. The newly developed "cut-and-paste" method has simplified the process and reduced the cost, but the "cut-paste" method requires the "electronic tattoo" sensor to be attached to the medical tape, thus increasing its thickness. , reduced breathability.
In view of this, Lunan Yan of the University of Texas at Austin, Huang Yongan of Huazhong University of Science and Technology, China, and their colleagues have improved this method to create a low-cost mesh "electronic tattoo" with a total thickness of only 1.5 microns. . They first pressed a piece of polyethylene terephthalate (1.4 micron) onto a temporary tattoo transfer paper and then applied a gold particle film to the plastic sheet. The researchers then cut the paper into an "electronic tattoo" using a computer-controlled knife that cuts paper, vinyl, and other materials into custom shapes; it can then be applied to human skin like a temporary tattoo. It is.
This tapeless design provides high breathability and flexibility for measuring skin moisture and temperature as well as ECG signals – from which heartbeat and respiration rates can be derived. Researchers say that tape-free "electronic tattoos" represent a step closer to one-time wearable technology.
What is a miniature slip ring? Miniature slip rings are rotary electrical connectors that allow power and data to be transferred between a stationary and rotating structure. They are often used in medical, military, and aerospace applications where size and weight are critical factors.
A miniature slip ring typically consists of two parts: a stationary housing and a rotating contact assembly. The contact assembly contains the brushes that make electrical contact with the rotating structure, as well as the rings that conduct current or data.
The housing can be made from any number of materials, including metals, plastics, and composites. It is typically designed to be as small and lightweight as possible while still providing adequate strength and durability.
The contact assembly is made from precious metals such as gold or silver in order to provide good electrical conductivity.
Technology improves with the continuous development of precision machinery. The more sophisticated the equipment, the smaller the volume will be. And the space that can be accommodated for installing the slip ring is also very small. The key parts of some equipment are quite a district. Especially in the high-end military, aerospace and aviation fields. 360-degree rotation is required to transmit current and signals. And the installation space is greatly reduced. It is to make the equipment work more smoothly. Therefore, it is necessary to design the slip ring to be small and exquisite. Otherwise, it won't meet the needs of the installation.
At the same time, we have moved with the continuous development of science and technology. Various high-end precision instruments have been developed. It requires the slip ring to transmit the current amount of general power. Also often undertake the transmission of weak electrical signals and various weak signals. The transmission medium is wider, and the number of loops of the slip ring is increasing.
