STRETCHABLE DEVICE
According to an aspect, a stretchable device includes a stretchable board, a sensor layer, and a counter electrode stacked in order. A direction in which the sensor layer is arranged when viewed from the stretchable board is a first stacking direction, and a direction opposite to the first stacking direction is a second stacking direction. The stretchable board includes a resin base material and an array layer stacked in order in the first stacking direction. The array layer includes: a first surface that is in contact with the sensor layer facing the first stacking direction; a recess that is recessed from the first surface in the second stacking direction; and a detection electrode that is arranged in the recess and comes into contact with the sensor layer only when the sensor layer moves in the second stacking direction.
1 . A stretchable device comprising:
a stretchable board, a sensor layer, and a counter electrode stacked in order, wherein
a direction in which the sensor layer is arranged when viewed from the stretchable board is a first stacking direction, and a direction opposite to the first stacking direction is a second stacking direction,
the stretchable board comprises a resin base material and an array layer stacked in order in the first stacking direction, and
the array layer comprises:
a first surface that is in contact with the sensor layer facing the first stacking direction;
a recess that is recessed from the first surface in the second stacking direction; and
a detection electrode that is arranged in the recess and comes into contact with the sensor layer only when the sensor layer moves in the second stacking direction.
2 . The stretchable device according to claim 1 , wherein
the stretchable board further comprises:
bodies that are spaced apart from each other; and
a plurality of hinges that couple the bodies, and
the recess is formed on the first surface of the bodies.
3 . The stretchable device according to claim 1 , further comprising:
a first stretchable resin layer that is arranged in the second stacking direction with respect to the stretchable board; and
a second stretchable resin layer that is arranged in the first stacking direction with respect to the counter electrode.
4 . The stretchable device according to claim 2 , further comprising:
a first stretchable resin layer that is arranged in the second stacking direction with respect to the stretchable board; and
a second stretchable resin layer that is arranged in the first stacking direction with respect to the counter electrode.
