At this year’s Sensors Converge, Epishine and NGK are showcasing a glimpse into the future of asset tracking, one that’s slim, smart, and self-powered.

The result of a collaboration between the two companies is the world’s thinnest asset tracker, compatible with FindMy and only 1.6 mm thick, powered entirely by ambient light. No cables. No charging ports. No battery replacement.

This innovative product concept combines two advanced technologies to create a fully self-powered tracker:

•          NGK’s EnerCera Pouch: A thin, high-performance lithium-ion battery ideal for compact IoT use cases, offering long life and excellent charge/discharge performance

•          Epishine’s Organic Indoor Solar Cells: Flexible, ultra-thin solar cells optimized to capture energy from ambient light.

Combined, they create a closed energy loop that keeps the tracker running continuously, and is perfect for use cases like logistics, healthcare, manufacturing, or retail where uptime and design flexibility are non-negotiable.

“By combining the ultra-thin technologies from both companies, we’re able to present the world’s thinnest FindMy tracker. It’s a strong example of our collaborative innovation in self-powered devices”, said Iwao Ohwada, VP at NGK.

Traditional tracking solutions rely on batteries that degrade, need replacing, or require complex maintenance schedules. This creates friction, waste, and unnecessary cost, especially at scale.

The Epishine-NGK tracker concept addresses these challenges head-on:

•          Captures energy from ambient light

•          Eliminates battery replacements

•          Enables an ultra-slim 1.6 mm form factor

•          Supports real-time tracking

•          Ready to scale across multiple industries

“This is a clear demonstration of how our collaboration with NGK is reshaping asset tracking, by removing the need for battery changes, enabling ultra-thin designs, and making light-powered, maintenance-free devices a reality”, said Anders Kottenauer, CEO at Epishine.
