ETAuto EV Conclave 2024: Printed electronics and their automotive application

Printed electronics is revolutionising the automotive industry, offering innovative solutions for enhanced functionality, safety, and efficiency. During the 9th edition of the ETAuto EV Conclave, Rafael Bennis, CTO at Naxnova Printed Electronics, shared insights on how this technology is poised to reshape the market.

“Printed electronics allows us to create conductive circuits that are thin, flexible, and capable of delivering additional features,” explained Bennis. Using their core expertise in screen printing, Naxnova Printed Electronics has transitioned from producing decals and 3D badging to pioneering printed electronics in India.

Enhancing electric vehicle efficiency

One notable application is in electric vehicles (EVs). “We’ve developed printed heaters integrated into vehicle components like door panels and armrests. These heaters improve battery efficiency by maintaining optimal temperatures during charging, especially in cold climates,” said Bennis. Additionally, temperature-sensitive sensors, printed on Kapton material, enable real-time monitoring of EV batteries. This innovation enhances the Battery Management System (BMS) by providing accurate temperature data, improving safety, and preventing thermal runaway.

Elevating safety standards

Beyond EVs, printed electronics are being integrated into safety systems. For example, Naxnova Printed Electronics is developing seatbelt reminders and other safety sensors to meet India’s upcoming 2025 legislation. “Imagine a system that detects weight on a bike seat to prevent children from accidentally starting the engine. Such safety features can reduce accidents significantly,” Bennis noted.

The technology also offers aesthetic enhancements, such as smart decals that illuminate using unique inks. These can improve visibility and safety in rural areas, providing both functionality and appeal.

Driving the future of mobility

Bennis emphasised, “We are ready to use our know-how and integrate printed electronics into final products, driving the future of mobility.”, further highlighting the importance of collaboration between technology innovators and automotive manufacturers. Such partnerships can pave the way for advancements in printing technology, enabling smarter, safer, and more efficient vehicles.
