One of the technical hurdles of wearable products is to eliminate the material and size limitations of the product. Given the current battery technology, wearable products still have no way out of battery shape for a more flexible shape design. However, recently researchers in the United States have developed a flexible, flexible textile battery that can not only power normal wearable devices but also be as flexible as ordinary cotton cloth.
Nazmul Karim, a researcher at the University of Manchester, is one of the researchers of this invention project. He said that the flexible textile battery created the birth of smart fabrics, making the wearable computer a reality. The researchers said that this kind of flexible battery device can power the wearable device, which will enable the wearable product screen to be directly used in the clothing fabric to achieve better health monitoring functions and wearability of the display device.
According to the researchers, flexible textile cells are based on low-cost graphene materials. The outside uses a simple screen printing technology. The electrodes are very stable due to the strong interaction between the ink and the textile, and they have good operational safety. Sex and long cycle life, the battery itself also supports fast charging, flexible materials allow water washing.
Researchers hope that their discovery will open the door to wearable smart computers and smart cloths, and they are currently writing this research paper. The University of Manchester is currently investing 60 million pounds in the construction of a large-scale graphene plant that will be completed next year and will provide international research facilities for the International Graphene Institute.
Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
SCSI-3
In 1995, the more high-speed SCSI-3, called ultrasci, was born, and the data transmission rate reached 20MB / s. It increases the synchronous transmission clock frequency to 20MB / s and improves the data transmission rate. If 16 bit wide mode is used, the data transmission rate can be increased to 40MB / s. This version of SCSI uses a 68 pin interface, which is mainly used on hard disks. The typical characteristic of SCSI-3 is that the bus frequency is greatly increased and the signal interference is reduced to enhance its stability.
There are many models of SCSI-3. Ultra (FAST-20) has a transmission frequency of 20MHz, a data bandwidth of 8 bits and a transmission rate of 20MBps
Ultra wide has a transmission frequency of 20MHz, a data bandwidth of 16 bits and a transmission rate of 40mbps
The transmission frequency of ultra 2 is 80 MHz, the data bandwidth is 16 bits, and the transmission rate is 80 Mbps
The transmission frequency of ultra 160 is 80 MHz, the data bandwidth is 16 bits, and the transmission rate is 160 Mbps
The transmission frequency of ultra 320 is 80MHz, the data bandwidth is 16 bits, and the transmission rate is 320mbps
The transmission frequency of ultra 640 is 160MHz, the data bandwidth is 16 bits, and the transmission rate is 640mbps
