Description
ウェアラブルデバイスは、使用者の体型に合わせて変形する機能を有することによって、より違和感なく装着することが可能となる。そのため、ウェアラブルデバイス用途として、変形可能なディスプレイ(フレキシブルディスプレイ)が提案されている。モバイル機器であるウェアラブルデバイスの用途を鑑みると、ディスプレイだけでなく、その他部品や電池も変形可能である必要がある。
図3(B)は図2(A)の構成を有する多層フィルム10の樹脂層211上に基材層217を設けた構成である。図3(C)は図2(B)の構成を有する多層フィルム10の樹脂層211上に基材層217を設けた構成である。基材層217は樹脂層211上に接着材層218を用いて積層すればよい。
本実施の形態では、折り曲げたフィルム10の間に実施の形態1とは一部異なる積層の組み合わせを複数収納する例を示す。
本実施の形態では、実施の形態1または2のいずれか一を用いて得られるリチウムイオン二次電池を組み込んだ電子機器の一例を示す。
蓄電装置を適用した電子機器の他の例として、生体情報を採取できる医療用の電子機器の例を示す。
