Regulatory Environment and Industry Standards (IEEE, IEC)

The regulatory environment and industry standards for wearable wireless energy harvesting devices are rapidly evolving as the sector matures and adoption accelerates. In 2025, the focus is on ensuring device safety, electromagnetic compatibility, and interoperability, while also addressing the unique challenges posed by integrating energy harvesting technologies into wearables.

The IEEE (Institute of Electrical and Electronics Engineers) plays a central role in standardizing wireless power transfer (WPT) and energy harvesting systems. The IEEE 802.15.6 standard, originally developed for wireless body area networks (WBANs), continues to be relevant, providing guidelines for low-power, short-range wireless communication in and around the human body. In parallel, the IEEE P2668 working group is developing standards for the evaluation of Internet of Things (IoT) solutions, including those with energy harvesting capabilities, to ensure performance and interoperability.

The International Electrotechnical Commission (IEC) is also active in this space, particularly through its Technical Committee 21 (Secondary cells and batteries) and Technical Committee 100 (Audio, video, and multimedia systems and equipment). The IEC 62827 series addresses wireless power transfer for audio, video, and multimedia equipment, and is being referenced for wearable applications. Additionally, IEC 62311 provides assessment methods for human exposure to electromagnetic fields from wireless devices, a critical consideration for wearables that harvest and transmit energy in close proximity to the body.

Industry consortia such as the Wireless Power Consortium (WPC) and the AirFuel Alliance are driving interoperability and safety standards for wireless charging and energy transfer.

Challenges: Efficiency, Miniaturization, and Integration

Wearable wireless energy harvesting devices are at the forefront of next-generation personal electronics, but their widespread adoption in 2025 and the coming years faces significant challenges in efficiency, miniaturization, and seamless integration. These hurdles are central to the development of practical, user-friendly wearables that can reliably power sensors, displays, and communication modules without frequent recharging or bulky form factors.

Efficiency remains a primary concern. The energy available from ambient sources—such as body heat, motion, or radio frequency (RF) signals—is inherently limited. Leading manufacturers like TDK Corporation and Vishay Intertechnology are actively developing advanced piezoelectric and thermoelectric materials to improve conversion rates. However, even state-of-the-art devices typically achieve only single-digit percentage efficiencies when converting biomechanical or thermal energy into usable electrical power. This restricts the range of applications to ultra-low-power electronics, such as health monitoring patches or fitness trackers, unless further breakthroughs are achieved.

Miniaturization is another critical challenge. Wearable devices must be lightweight, flexible, and comfortable for continuous use. Companies like ams OSRAM and STMicroelectronics are pushing the boundaries of microfabrication, integrating energy harvesters with microcontrollers and wireless modules on a single chip or flexible substrate. Despite these advances, shrinking the size of energy harvesting modules often leads to reduced power output, creating a trade-off between device form factor and functionality. The integration of nanomaterials and thin-film technologies is promising, but mass production at scale remains a technical and economic challenge.

Integration with existing wearable platforms is equally complex. Energy harvesters must coexist with batteries, sensors, and communication circuits without causing electromagnetic interference or compromising device reliability. Analog Devices and NXP Semiconductors are developing power management integrated circuits (PMICs) specifically designed for energy harvesting, enabling more efficient energy storage and distribution. However, ensuring compatibility with diverse wearable architectures and maintaining robust wireless connectivity—especially as 5G and future wireless standards proliferate—requires ongoing innovation in circuit design and system integration.

Looking ahead, the sector is expected to see incremental improvements in material science, circuit miniaturization, and system-level integration through 2025 and beyond. Collaborative efforts between material suppliers, semiconductor manufacturers, and wearable device brands will be crucial to overcoming these challenges and unlocking the full potential of wearable wireless energy harvesting devices.
