MobilityAD/ADAS
In the connected and AD/ADAS fields, it supports the enhancement of
sensing functions and high-speed communication from the material aspect.
Polymer Waveguide (PWG) for In-Vehicle Network
(Under Development)
of next-generation harnesses (optical harnesses).
Advantage
The optical wiring is lighter than the electrical wire harness, has no noise, and can reliably distribute a large amount of information into the automotive
