Exploring new frontiers
within human bodies
with new vital signs

Data is just data without interpretation
We use our medical expertise and technology,
and transform data into insight
that adds value to our healthcare and daily life.

Mission

Sweat inside every one of us
It is now attracting more attention than ever as a new form of vital sign.

We are commercializing the world’s first wearable device that
monitors change in amount fo lactic acid within our sweat.
With this device, we aim to medically assess and quantify every physical activity.
We believe there still exsits unknowns within our body.
We use our medical expertise and technology,
and transform data into insight
that adds value to our healthcare and daily life.

Technology

We visualize “fatigue” from the change in lactic acid content in sweat.
Our unprecedented technology, powered by chemistry and electronics.

Ever increasing number of heart failure patients on cardiac rehabilitation program.
Professional athletes going through vigorous training everyday.
Workers exposed to high-risk, high-physically demanding environment.
We all require better understanding of “fatigue” one way or another.
Our device will let us simultaneously monitor the lactic acid content in sweat,
which changes depending on the degree of physical activity.
By delivering our technology, we will present new understanding of body functions,
and bring new lifestyle, new form of healthcare, and new ways of enjoying sports.

Lab

We aim to expand the possibilities of human body with sweat.
And our lab is working on various projects.

Company

Medical understanding and social development.
We don’t just collect data, but use the data.

There exists technologies to acquire data, and are lot of research projects on vital signs.
But they are never used in our real life.
We don’t let data sit as data.
Everyday, we bring sit together with medical experts,
continuously assessing data on hand
to bring meaningful changes in our life.
