通过触摸屏,测体温
问题描述:
我读的地方,体温可通过触摸屏,因为不同的体温引起不同电荷的电容screen.Is可以衡量?如果是的话,怎么能值被记录下来并转换成相应的温度?
I read somewhere that body temperature can be measured through touch screen since different body temperature induces different charge on the capacitive screen.Is it possible? If yes,how can the value be recorded and converted to corresponding temperature?
答
不同电荷的设备意味着不同的坐标。所以你不能说完全 - 是它的温度变化,或者用户只需移动手指
Different charge for device means different coordinates. So you can't say exactly - is it temperature changed, or user just move his finger.
实际上,电荷不会依赖于温度这么多。
Actually, charge doesn't depends on temperature so much.
