bionic hand / 生体工学の手

Inventive Britaini-LIMB
inventor:  David Gow, stamp design: GBH

I noticed that I have been featuring hands on stamps over a year – well, long enough.  So, it is the last one for this time and an artificial hand.  This hand with lots of tiny motors is invented to help people without their own hand and operated by electrical pulses in the muscles of remaining part of the arm.

The stamp designer used its blueprint, and added its electrical movement of ‘wish’ – signals released from the user’s brain – which triggers the motors to move fingers.  It is not easy to explain such a complicated idea in the space of a stamp, but this is delivering its sense of motion and complexity.

手の切手ばかりを一年以上も掲載していることに気づき、これを最後の1枚に選びました。人工の手です。生まれつき手がなかったり事故で手を失った人のために考えられた、たくさんの小さなモーターで関節を動かして細やかな動作をする手。脳から発せられる電気的な波動が腕に伝わるのをコンピューターがとらえ、モーターを動かすのだと説明しています。すごい。

切手のデザイナーは、あまり美しくない実物ではなく、設計図をイメージに使っています。装置やしくみを小さな切手に表現するのは難しそうですが、、、メカニズムの複雑さと、電気的な信号が行き交う雰囲気は、伝わってきます。
