Will IME Be the Path for Printed Electronics to Break Into Automotives

Why It Matters

Embedding electronics directly into molded parts cuts vehicle weight and wiring complexity, a critical advantage as electric vehicles demand efficient thermal management and design flexibility. Early adoption could reshape supply chains and accelerate EV adoption.

Key Takeaways

• Kronos Mechatronics won LOPEC 2026 Startup Award for business potential
• IME embeds conductive traces, cutting wiring weight in vehicle interiors
• 3‑D printed electronics enable curved surfaces and integrated lighting
• EV heating solutions benefit from IME‑based heat‑mat and radar warming
• Industry expects automotive IME adoption beginning 2027‑28

Pulse Analysis

The recent LOPEC 2026 showcase highlighted in‑mold electronics as a bridge between printed electronics and traditional automotive wiring. By polymerizing conductive inks directly within structural components, IME eliminates the need for separate harnesses, delivering up to 30% weight savings in interior modules. This integration also reduces assembly steps, lowers material costs, and opens new aesthetic possibilities such as seamless ambient lighting and embedded touch sensors, aligning with automakers’ push for premium cabin experiences.

For electric vehicles, thermal management is a top priority because they lack the waste heat of internal combustion engines. IME‑based heating mats and radar‑warming strips demonstrated by companies like MackSmaTec provide localized temperature control without adding bulky elements. Conductive‑ink solutions from Henkel and others further enable battery‑warming panels that improve range in cold climates. Coupled with the ability to embed LEDs and color‑changing elements, IME supports both functional and brand‑defining lighting schemes that were previously impractical on curved surfaces.

Market forecasts from IDTechEx predict the automotive IME segment will reach multi‑billion‑dollar revenues by 2035, driven by OEM commitments to lighter vehicles and faster assembly lines. However, scaling challenges remain, including ink reliability, mold‑tooling costs, and certification for safety‑critical systems. Investment in pilot programs slated for 2027‑28 will be crucial to validate long‑term durability and to integrate IME into existing supply chains. Companies that secure early partnerships with tier‑1 suppliers are likely to capture the most value as the technology moves from prototype to volume production.
