Sumitomo Riko to Exhibit at the Automotive
Engineering Exposition 2021 Online- Exhibiting five products in the “Sensing” and “Thermal Management”
fields relating to CASE –Sumitomo Riko Company Limited (Headquarters: Nakamura-ku, Nagoya-shi;
President & CEO: Kazushi Shimizu) will exhibit at a joint booth together with
Sumitomo Electric Industries, Ltd. (Chuo-ku, Osaka-shi) and Sumitomo Wiring
System, Ltd. (Yokkaichi-shi, Mie Prefecture) at the Automotive Engineering
Exposition 2021 Online to be held from May 26 (Wed).
As the auto industry enters a period of major change, including the increase ofelectric vehicles (EV) and the acceleration of initiatives for “CASE*” to promote theadvancement of technology for self-driving cars, Sumitomo Riko is actively engaged
in the R&D of new products and materials utilizing our core competence, polymer
materials technology and comprehensive evaluation technology.
At this online exhibition, we will show products of the Sumitomo Riko Group witha particular emphasis on “C: Connected” , “A: Autonomous” and “E: Electric”.
In the sensor field, we will show a “Film Decoration Ornament”, “CompartmentSpace Device” and the “Driver Monitoring System” as products to contribute to “C:Connected” and “A: Autonomous”.
In the thermal management field, we plan to show the “High Performance Heat
Insulation: Finesulight™” and “Heat Insulation for Battery Cell” as products tocontribute to “E: Electric”.

C：Connected>> Film Decoration Ornament (Development item/first time exhibited)
This is an ornament which can be used on exterior
trims such as emblems and interior trim components.
It is a unique type of film that can even be affixed on
intricate and uneven surfaces. It is environmentallyfriendly as it requires less solvent than paint, andthrough the use of a special metallic film, it allows
passage of radio waves and optical transmission and issuitable for millimeter-wave radar compatible
emblems and illuminations. We are also in the processof developing an ornament with a built-in sensor byadding the film to an extendable sensor.

A：Autonomous>> Compartment Space Device (Development item)
This compartment space device has been improved
from the model previously displayed and now includes
a switch that appears when the user wishes to operate
the device. Its simple and functional design
contributes to more intuitive use and comfortablemobility. A switch will appear when the user’s hand isdetected near the detection area and this is operated
by an internal flexible “Smart Rubber (SR) sensor”.
It also contains a haptic interface that sends avibrating a signal from the switch through an actuator
made from Smart Rubber (SR), a special rubber that
conducts electricity. Utilizing SR’s characteristics, SR
can express various kinds of vibrations, such as strong
and weak vibrations and different rhythms.

>> Driver Monitoring System (Prototype)Made into the shape of a cushion, SR sensors are
installed into the surface of the driver’s seat to detectthe driver’s heart rate, breathing, body motion andother factors based on changes in pressure on the seat.
The system estimates fatigue, drowsiness, signs ofsudden illness and other conditions from the observed
data and can connect to services such as alerting thedriver, generating the driving support system orsending an external notification.

E：Electric>> High Performance Heat Insulation “FinesulightTM”(First time exhibited)
Utilizing polymer materials technology, we made ahigh-heat insulating filler (silica aerogel) containing
nanopores small enough to block the passage of air,
into a coating liquid. Then, by coating base materials
such as non-woven fabric and molded resin at a levelof still air or higher. As mobility moves toward electricvehicles (EV), all energy needs to be supplied byelectricity. As such, this product increases theeffectiveness of cooling and heating and contributes toextending cruising distance. In addition to use invehicles, we anticipate that this can be used in various
fields including household appliances, housing andfood delivery.

>> Heat Insulation for Battery Cell
(Development item/first time exhibited)
We have improved the Finesulight™ compoundbonder technology and developed an insulator for
lithium-ion batteries in electric vehicles (EV) which
can withstand high temperatures of several hundred
degrees celsius. It suppresses heat chains fromdeveloping between adjacent cells in the case of
extraordinary heat surges and avoids major incidents
which can cause fires in the vehicle. We aim tooptimize this insulator by making further adjustments
to the insulation performance, hardness and otherfactors in line with customer requirements.

<Cautionary Notes>
The actual exhibition in Yokohama, which was scheduled for May 26 to 28, wascancelled.
