The wearable antennas may have potential application in many areas. According to the speaker, which of the following is NOT one of them? [br]
Humans may become walking antennas for remote monitoring and mobile communications — with the help of a recent research to produce antennas integrated into clothing.
Still under development, the wearable antennas have potential application in biomedical monitoring, sports analysis, military and emergency communications.
The antennas can be incorporated into clothing using computerized embroidery into conductive fabric. A range of different shaped and sized antennas can be produced using altered patterns in the embroidery.
Wearable electronic systems for a range of communications applications have grown exponentially over the last few years. But the problem is these devices need very efficient antennas to communicate with the data receiver and to power the sensors being used — especially with radio frequency identification (RFTD)systems where the radiowave has to power the whole system.
Another issue is that the human body does not make a good environment for our antenna. We are a container of saltwater from an electromagnetic point of view; we absorb and change the characteristic of the signal, rather than transmitting it efficiently.
The solution being developed is a T-shirt made of conductive metallised fabric which is low-cost, flexible and lightweight. It doesn’t deteriorate easily and is washable, with the antenna embroidered onto the textile.
The difficulty of incorporating the electronics has been overcome with using snap-on buttons which form a connection between the textile antenna and the sensor device. These can easily be removed for washing.
The electronics can’t be directly integrated into the T-shirt because they would be uncomfortable to wear and aren’t water-proof. A recent research finding has shown that these readily available snap-on buttons used commonly on clothing make very reliable connections between the antenna and the electronics.
选项
A、The wearable devices need very efficient antennas to communicate with the data receiver.
B、The wearable devices need very efficient antennas to power the sensors being used.
C、The human body does not make a good environment for antennas.
D、All of the above.
答案
D
解析
根据原文“But the problem is these devices need very efficient antennas to communicate with the data receiver and to power the sensors being used”,可以确定A和B都是正确的;再根据原文“Another issue is that the human body does not make a good environment forour antenna.”,可以确定C也是正确的,因此选D。
