ハサミで切れるワイヤレス充電シートや、水溶性の流路に液体金属を流し込む 3D 印刷など、電子デバイスを誰でも作り変えられる製造手法を設計する。
電子デバイスは一度作ると形を変えられない。センサの最適な位置は人によっても用途によっても違うのに、導電糸で縫い付けてしまうと後から動かせない。
そこで、作り変えられる作り方そのものを設計している。H 木配線のワイヤレス充電シートは、ハサミで切っても残った部分が動き続ける。水溶性樹脂で 3D 印刷した流路に液体金属を流し込めば、水に溶かして液体金属を回収でき、4回の作り直しでも 98% が戻る。機械編みで電力と通信のバスを布に織り込み、センサを磁石で付け替えられるようにすれば、位置合わせを何度でもやり直せる。
