Thread actually generates a small amount of electricity
when pressure is applied.
This electricity makes it possible to detect various movements,
such as pull, rub, and twist, depending on the stitching method.
YUWAERU was developed based on this technology.

The thread feels something.
It is all about the piezoelectric fibers.
YUWAERU broadens the possibilities of what fiber can do in fashion,
entertainment, sports, traditional handcrafts
and products in your everyday life.
PROTOTYPE
PROTOTYPE 01
PRESENT RIBBON
The moment you untie the PRESENT RIBBON –
Suddenly pictures appear, light shines,
music plays or the giftbox dances. A surprise happens.
Gifting moments become more memorable.
It can bring you and your loved ones much stronger.
Hold
Loosen
Surprise!
VISION
Fibers are so much a part of our daily lives
that we don't even notice them. YUWAERU will work with partners
to update everyday experiences with piezoelectric fibers.

Once YUWAERU is weaved in...
Clothes become devices which can be operated without a hand.
Empty seats on trains can be searchable before arriving..
Pillows can tell you how well we sleep.
NEXT
- 01
Mood accessory
It is well-known that a dog’s tail expresses their emotions.
This innovation will sense the tail movements
and we can know more about what dogs
are thinking and feeling. - 02
Wearable synthesizer
You can play a musical instrument by dancing.
Every movement of the piezoelectric fiber is expressed
as an electrical waveform, converted into sound,
which can then be turned into a synthesizer. - 03
Connected cheering towel
You can see the emotion of fans.
The technology recognizes how each person waves the towel.
You can track the heat real time and reflect the fans’ energy.
