Weaving a Smarter Future

Flying cars and time machines.
We can’t yet hear the footsteps of the future we dreamed of in the 20th century.
What arrived instead was a society in which anyone could access information from around the world from the palm of their hand.
Today, we’re experiencing a future that extends beyond our imaginations.

Our interactions with computers will continue to become simpler.
Computers that understand our intentions without us lifting a finger or speaking a word—
becoming extensions of our physical bodies.
Such a future is not so far away.
LEAD SKIN is weaving a future brimming with possibilities.

What is LEAD SKIN?

LEAD SKIN is a new type of conductive fiber manufactured
with dyeing techniques.

In addition to mitigating some of the problems of conventional bioelectrodes, such as discomfort and inflammation caused by wearing them, and performance issues caused by perspiration, the entire surface of each fiber is coated with a film of conductive material that enables better, more homogenized conductivity.


1. High, Homogenous Conductivity

By applying a film-based, rather than a particle-based conductive coating, we are able to add high1, homogenous conductivity throughout the fibers of the material. This technology can be applied not only in materials for transmitting electricity but also in products such as electrical impedance tomography (EIT) devices, including pressure distribution sensors and multi-touch sensors.

2. Safe, Clean, and Long-Lasting

In addition to being silky smooth to the touch, LEAD SKIN has also earned the world’s highest class safety standard—Oeko-Tex® Standard 100, class I2—certifying that it contains no harmful chemicals. As washing does not significantly deteriorate its performance, it can be used safe and clean, for a long time.

3. Antibacterial and Antiviral Performance

LEAD SKIN’s conductive coating can also quickly inactivate bacteria and viruses3. Under the pandemic situation of COVID-19, our coating helps promote health and safety by offering high antibacterial and antiviral performance in interfaces that are touched by many people.

4. Protection from Electromagnetic Waves

Cell phones and other wireless communication devices are ubiquitous recently worldwide. Although the speedy communication enabled by high-frequency bands has made our lives convenient, we must take precautions to avoid the increasing risks associated with electromagnetic waves, such as close exposure. LEAD SKIN’s exceptional safety makes it suitable for use as an electromagnetic shielding device4 that can be worn directly on the skin.

5. Diverse Application Possibilities

Our unique conductive coating method, LEAD SKIN TECHNOLOGY, is based on dyeing techniques. It can therefore be applied to a variety of fibers, including polyester, synthetic leather, and non-woven fabrics. By combining our technology with other materials, we can also create compound coatings. We work with our customers to develop products that meet their specific needs, including price, texture, and function.
