Professor Lee Byung-hun’s research team from the Department of Biomedical Engineering, School of Electrical and Biomedical Engineering at Hanyang University has announced the development of an innovative wireless power and data transmission system. This technology allows multiple IoT(Internet of Things) devices to operate permanently without replacing batteries, even in underground environments where radio waves struggle to penetrate.

In existing smart agriculture or 토토 카지노 facility management sites, the fact that soil and concrete block radio frequency(RF) signals has posed a major challenge. The high maintenance costs, such as having to dig up the ground to replace sensor batteries or constructing expensive wired networks, have been significant barriers to commercialization.

To solve this, Professor Lee’s team introduced a 'Magnetic Induction Domino Structure.' This method arranges coils at specific intervals to relay power and data over long distances, similar to crossing stepping stones, even in radio shadow areas.

Specifically, the team devised the world's first 'Load-Resonator Interleaved(LRI)' 토토 카지노. Currently, existing technologies face a chronic problem. When sending power to multiple devices while simultaneously receiving data, interferences in signals would cause failures in communication. The research team solved this through an independent control 토토 카지노 for power and data paths. In actual soil environment verification tests, they confirmed that multiple sensors operated stably up to a distance of 77 cm.

Furthermore, this 토토 카지노 has a significant ripple effect as it enables the construction of 'maintenance-free' infrastructure. When power is supplied wirelessly from the surface, underground sensors can operate semi-permanently and transmit real-time data. This is expected to bring revolutionary changes to the management of large-scale farms and underground facilities. It also holds high potential for expansion into the biomedical field, such as implantable medical devices or brain science research, where there are difficulties in battery replacement and penetration of radio waves.

Professor Lee Byung-hun emphasized, "This research holds academic and industrial significance by simplifying the system structure while simultaneously achieving the dual goals of power supply and data communication. Beyond smart farms, this will become a foundational technology applicable to all extreme environments where human reach is limited, such as underwater monitoring of marine environments and wireless charging for implantable devices."

This study was supported by the Korea Institute for Advancement of 토토 카지노(KIAT) Industrial 토토 카지노 Innovation Program(RS-2022-00154983, Development of a self-powered sensor platform for low-power sensors and operation), the Ministry of Science and ICT(MSIT) AI Semiconductor Advanced Talent Cultivation Program(IITP-(2026)-RS-2023-00253914), and the Brain Science Leading Interdisciplinary 토토 카지노 Development Program(RS-2024-00398460).

The paper, Load-Utilized Constant Voltage Wireless Power and Data Transfer System for Multiple IoT Devices in RF-Challenging Environments, was recognized as a key 토토 카지노 for solving communication challenges in extreme environments like smart farms and underground power conduit monitoring. It was published online in December 2025 in IEEE Transactions on Industrial Informatics, a world-renowned journal in the field of industrial informatics.
