No matter how much digital technology advances,
not a day goes by when humans don't touch things.
Soft. Hard. Smooth. Coarse.

We live with the sense of touch every day,
even every minute and every second.
When we touch something, sometimes we will feel comfort,
and other times discomfort or pain.

If only we could eliminate the "mismatches" that occur between people
and things countless times each day
in all kinds of situations, from medical care and nursing to sports.
If only we could make those points of contact between people and things more gentle.
It was out of that desire that HUMOFIT™ was born.
The origin of our development lay in the concept of "being close to people."

Developed by Mitsui Chemicsals, HUMOFIT™ is an entirely new material
that detects a person's body temperature and gently wraps around the body that touched it.


  • Shape memory

    HUMOFIT™ is a new material
    that can bend, fold,
    twist or stretch without force being applied.
    Although it is stiff against an initial stress,
    it stretches a little at a time,
    and then gradually returns
    to its original shape like felt.

  • Temperature dependence

    HUMOFIT™ is temperature dependent.
    It is a new material
    that becomes flexible when heated,
    It can be shaped to fit the body
    with a person's body temperature,
    or heated up and folded compactly
    for easy transportation.
    When cooled down, it becomes hard.
