Powering the AI Hardware Evolution: Grepow to Showcase Next-Gen Shaped Battery Solutions at Viva Tech 2026

Viva Technology 2026 (Viva Tech 2026), Europe’s premier technology event, will take place in Paris from June 17 to 20. As French President Emmanuel Macron has noted, the event has become the ultimate barometer of cutting-edge global technology trends. As a global leader in the field of customized micro and specialty batteries, Grepow Batteries will be attending this event. At Booth 3B21-003 in Pavilion 7, we will join innovators from around the world to explore the future of energy for edge AI and next-generation wearable hardware.

Trend Insights: Physical AI Drives a Strong Comeback for Hardware

This year’s Viva Tech 2026, themed “Artificial Intelligence: Impact, Not Illusion,” signals that the global tech industry is shifting from a pure software gold rush toward a focus on “Physical AI” in real-world scenarios and a major resurgence of hardware. From smart rings and AI-powered glasses to various smart devices, AI is accelerating its move out of the cloud and deeply embedding itself into physical objects, ushering in the strongest hardware revival of the digital age.

Our Forecast: Energy Is the Ultimate Bottleneck for Edge AI

The inherent tension between “Physical AI” and extreme miniaturization is pushing energy consumption to the forefront as the ultimate bottleneck in hardware innovation. Edge AI requires algorithms to run locally and process sensor data in real time, leading to an exponential increase in device power consumption.

However, to ensure maximum comfort and aesthetic appeal, the internal space of devices such as smart rings and glasses has been compressed to the millimeter level, featuring highly irregular, streamlined geometric shapes. Traditional standard square battery cells cannot utilize dead-space areas, and devices cannot be forced to conform to the battery’s shape—batteries must instead adapt to the device’s form. This is precisely why custom-shaped battery solutions have become a standard feature in hard tech.

Grepow’s Solution: Building a Solid Foundation for Physical AI with High-Energy “Shaped Batteries”

Addressing these industry pain points, Grepow unveiled a new shaped battery solution at Viva Tech 2026:

Smart Rings: Stacked Curved Batteries

• Stacking Process Breakthrough: Utilizing proprietary advanced stacking technology, hot-press molding eliminates internal mechanical stress, ensuring safety and a cycle life exceeding 500 cycles.

• Capacity Increase: Perfectly conforms to the inner surface of the ring and eliminates dead zones. Capacity increases by up to 30% within the same compact volume (e.g., from 16mAh to 21mAh), ensuring AI health algorithms remain online 24/7.

Smart Glasses: Ultra-Slim Batteries

• Pushing the Width Limits: Micro-high-precision manufacturing processes compress cell width to its physical limit, allowing for seamless, invisible integration into narrow temple arms while balancing technological functionality with aesthetic design.

• High-Voltage Fast Charging Technology: Supports 4.35V/4.4V high-voltage systems to unlock high energy density; features 1C–30C fast charging capabilities, enabling users to return to the AI-powered world at any time.

Edge AI Hardware: Custom Batteries for Any Shape

• Embracing the exhibition’s “Risk, Build, Scale” entrepreneurial spirit, we offer highly flexible, full-category customization. We cover any irregular geometric shapes—including circular, triangular, ultra-thin, C-shaped, and D-shaped (thickness ranging from 0.4mm to 8mm)—precisely matching the internal irregular structures of various hardware components such as AI wearables and smart badges.
