消しゴム大のホルター
昨日、ホルター(脈拍24時間計測器)を装着してきた。計測器を見て驚いた。とても小さい。消しゴムぐらいの大きさで、煩わしいコードは着いていない。一年ぐらい前に装着したときは、スマホぐらいの大きさで、コードが7本ぐらいついていた。その前の旧式ホルターは、もう15年ぐらい前だったが、弁当箱ぐらいの大きさだった。
科学の進歩は著しい。何でも、ますます小型化していく。テレビで先日見たが、チップが手の甲に埋め込んであり、それで支払いを済ませていた。身体の中にスマホを埋め込む時代が来るのかもしれない。
A Very Small Holter Monitor
I went to a hospital to wear a holter monitor, a portable device for cardiac monitoring for 24 hours. The device was very light and as small as an eraser, about 6 by 6 centimeters. It did not have any troublesome leads that attach your body. About a year ago, the device was as large as a smartphone with 6 or 7 leads. About 15 years ago when I first wore a holter monitor, the machine was heavy and as large as a big lunch box.
The development of science is marvelous. Things are getting smaller and smaller. The other day I saw a TV program in which a man was paying by putting his back of his hand on a machine at a store. A micro-chip was implanted in his hand. Sooner or later, a computer as large as a chip will be implanted in your hand. It is spooky, isn’t it?
