Expanse of Consumer Electronics Industry to Create a Hotbed of Opportunities for Optical Rectenna Market Players

A rectenna, technically a rectifying antenna, remains in demand for its capability to convert AC electromagnetic (EM) waves into DC electricity. Optical rectennas will continue to witness solid demand on the back of their potential to contribute toward the renewables sector. They are also popularising because of their flexible radiofrequency (RF) that converts light energy into electricity, and enables it to aid in wireless power transmission. Predominantly fuelled by the most common applications like powering electronic circuits, and recharging batteries, the global optical rectenna market has been on an upward growth trend on account of the ballooning consumer electronics industry. With innovative devices debuting the world of smart mobile electronics, optical rectenna will most likely see spiralling sales. The mushrooming market for wearable electronic devices holds the promise to bring in multiple opportunities in front of optical rectenna makers.

Optical Rectenna Market to Gain from Establishment of IoT, and Medical Implants

Increasing inclination toward wireless charging solutions for mobile devices will also remain among the key boosters to market growth. Wide application possibilities in remote battery charging in various sensor networks employed in Internet of Things (IoT)-enabled applications in the field of automobiles, smart building, and medical are expected to push rectenna penetration in the global market. With accelerating development of smart cities, smart buildings, smart homes, and smart devices are also set to have a moment, which is projected to push optical rectenna sales further. With 5G market firming up at a brisk pace, optical rectennas are more likely to experience soaring demand in the near future. Rocketing popularity of implantable medical devices will remain another strong push factor for the growth of the optical rectenna market. Although the unlimited lifespan of rectennas remains their prime demand driver, the relatively expensive cost point, and relatively less power output continue to be the key challenges in front of manufacturers.

An Ambitious Application Lookout Continues to Elevate Market Prospects of Optical Rectennas

There is a wide application potential of optical rectennas in areas like energy harvesting, wireless power transmission, proximity cards, and contactless cards, of which energy harvesting has been perceived as a highly lucrative segment. However, optical rectennas are also believed to hold a significant application potential to be utilised in powering up the devices enabled by IoT in the near future. Electricity production from the scavenged thermal energy is claimed by researchers to be possible with the employment optical rectenna.

There has been excitement within the new-age energy circle regarding thermoelectric generators over the recent past, which critically demands a highly efficient, and effectively functioning system. Here, researchers are looking at optical rectennas to aid in harvesting heat in an economic way. This, and more such research findings will continue to supplement the global optical rectenna market revenue over the forecast period. While researchers worldwide have been focusing on better theoretical understanding of the exact mechanism of rectennas, especially optical variants, they are simultaneously exploring different possibilities of the operational optimisation of these antennas. The objectives are highly ambitious, including pushing application of these rectennas in spacecrafts.

North America at Forefront; China Leads Thriving Market in Asia Pacific

North America, the globally leading regional market for optical rectennas, is upheld by solid technological developments, and brisk spread of wireless technologies. Extensively growing adoption of radiofrequency identification (RFID) technology at all types of security checkpoints is also predominantly driving market expansion across the North American region, especially in the US. The flourishing IoT landscape, and high growth outlook of smart/connected devices further uplifts the scope for optical rectenna penetration.

On the other side, banking on exceptional proliferation of wireless technologies, Asia Pacific is set to exhibit significant opportunistic potential for optical rectenna manufacturers. The region, especially China, houses the world’s largest consumer electronics industry, potentially the most significant consumer segment for rectennas in making. The region also continues to reap benefits of the presence of multiple leading rectenna making companies. This clearly points to the high market attractiveness of Asia Pacific as a region, as well as a strong global contender in terms of optical rectenna consumption over the forecast period. India, and Japan also represent thriving potential markets for key companies in the optical rectenna market, mainly owing to an upsurge in sales of energy harvesting systems that make use of rectennas.

Research, and Product Innovations Drive Competition in Global Optical Rectenna Market

Some of the key players stirring competition in the global optical rectenna market include Allis Communications Co., Ltd., AVX Corporation, API Technologies Corporation, Antenova Limited, CoolCAD Electronics, LLC, Murata Manufacturing Co., Ltd., Nihon Dengyo Kosaku Co. Ltd., Ducommun Incorporated, AH Systems Inc., FURUNO Electric Co., Ltd., and AR RF/Microwave Instrumentation. With innovation product developments on priority to cater to an exploding consumption potential of the consumer electronics industry, leading companies are expected to continue their investments in strategic partnerships.

Collaborations over R&D is likely to be another strong growth strategy adopted by global market leaders in an effort to conquer newer areas of commercial applications of optical rectennas. A lot has been explored, and discovered in the world of research as several universities, research institutes, and individual start-ups continue to achieve improved rectenna performance for greater compatibility with low-power devices, with an ultimate aim to identify novel application segments in the near future.

Recent Notable Developments in Optical Rectenna R&D

  • In 2015, a team of engineers working with the Georgia Institute of Technology developed optical rectennas that make use of carbon nanotubes. These nanotubes serve as the antennas to capture solar light, or light from the other sources for conversion of energy
  • A novel rectenna was developed in collaboration by the MIT, and University of Madrid in 2019 based on the conversion of the energy from Wi-Fi signals into electricity. The team utilised 2D materials that are relatively inexpensive, and flexible, and looks forward to aid in powering medical devices, wearable devices, and large-area electronics
  • In an effort to overcome the key challenge facing optical rectenna makers, i.e., low efficiency, a research team at the University of Colorado, Boulder (US) recently came to the fore in 2021 with a novel means to up their efficiency making them potentially viable for large-scale practical usage. The study encompasses harvesting energy from wasted heat to ultimately boost the conversion efficiency of optical rectennas by 100 to 1000folds. The study that employed the resonant tunnelling process further concludes that experimentation for material innovations could be one more way to push the rectennas’ conversion efficiency. A lot still remains to be studies, discovered, and explored to have any practical application value in real world
