Space Power Technologies to Showcase Microwave Wireless Power Transfer at IIFES2025

Space Power Technologies to Shine at IIFES2025

Space Power Technologies, a startup emerging from Kyoto University, is excited to announce its forthcoming participation in the Innovative Industry Fair for E x Smart (IIFES2025). The event will take place from November 19 to 21, 2025, at Tokyo Big Sight. The company will showcase its cutting-edge microwave wireless power transmission system, capable of delivering several watts of power over a distance of one meter.

Background: Addressing Power Supply Bottlenecks in Manufacturing

In the face of significant challenges, the manufacturing industry is undergoing a transformation propelled by the quest for competitiveness, the AI revolution, and a chronic labor shortage due to the aging population. The shift to a 'new manufacturing' paradigm centered on automation and data utilization is urgent. To facilitate real-time data collection and analysis from existing equipment, the establishment of IoT connectivity and sensor networks is essential. However, several obstacles hinder progress in this area:

- Burden of Wiring for Retrofitted Sensors: Installing power cables for thousands of IoT sensors poses a substantial burden.
- Maintenance Costs of Battery Replacement and Charging: These costs lead to increased labor expenses and operational downtime.
- Restrictions on Power Supply to Movable Objects: Cable interference imposes limitations on robotic and conveyor systems' movements.
- Sensor Downtime Risks: Battery life can result in measurement interruptions and data loss.

These issues create a bottleneck that hampers digital transformation (DX) and smart factory advancements. As a result, the industry yearns for full wireless and cable-free solutions.
