ポリウレタン繊維をナイロン繊維でカバーリングした糸を用いて、幅6.0cmの平ゴムを長さ65cmのベルトをにし、作製したベルトに実施例1と同様にして作成した電極101aおよび101b、コネクタ102、配線部103aおよび103bを取り付けた生体信号検出用ベルトを作製した。
電極101aおよび101bの位置をアンダーベルト114でなく、前身頃104aの左右胸部下に配置する以外は実施例1と同様に生体信号検出衣料を作製した。
前身頃104aおよび左右後身頃104bのパターンを変更し、前身頃104aのネックポイントAからアンダーベルト114上部までの長さ(500A)が18cmとなる以外は実施例1と同様に生体信号検出衣料を作製した。
前身頃104aおよび左右後身頃104bのパターンを変更し、前身頃104aのネックポイントAからアンダーベルト114上部までの長さ(500A)が40cmとなる以外は実施例1と同様に生体信号検出衣料を作製した。
衣服のパターン・構成をTシャツに変更し、電極101a、101bの位置を左右胸窩下に配置する以外は実施例1と同様に生体信号検出衣料を作製した。
