Flexible Generators Market

Flexible Generator to Benefit from Rocketing Personal Electronics Sales

Unlike conventional power generators that are extensively used as backup power in commercial, and residential set-ups, flexible generators were invented in 2012 (by Wang et al.) and find application in power wearable devices, and sensors. The flexible power generation technology is typically used in piezoelectric devices such as cell phones, grill igniters, diesel fuel injectors, ultrasonic transducers, some printers, vibration sensors, certain printers, humidifiers, electric toothbrushes, and some microphones. With the soaring adoption of these triboelectric nanogenerators (TENGs) for wearable devices like smart watches, the flexible generators market is likely to expand at an impressive rate through the period of forecast.

As the flexible power generation is based on the principle of harvesting energy from movement such as human activities, blowing wind, mechanical vibrations, and rotating tires, the demand for flexible generators will remain higher among small electronics manufacturers worldwide. An exploding market for wearable electronic devices, especially smart watches, health monitors, fitness trackers, and GPS trackers, is projected to be a major booster to market expansion in the near future. Moreover, flexible generators are likely to gain strong ground with rapid proliferation of wearable electronic skin technology worldwide. Surge in popularity of bendable/flexible displays within the electronics realm highlights another healthy opportunity for flexible generator manufacturers. Incessant adoption of light emitting diode (LED) screens for some of the bestselling electronics categories also creates a lucrative investment pocket. Potential application in smart homes, and smart clothing underscore a high-value opportunity emerging on the horizon for TENG manufacturers.

Growing R&D Efforts Uplift Market Prospects of Flexible Generators

Being a decade-old technology in picture, TENGs continue to provide an interesting area of research to scientists, as well as end users. Flexible power generation is increasingly being perceived as a novel technology, and a lot of research prevails to discover newer methodologies for its improved output performance. Besides personal electronic devices, myriads of application areas include self-powered systems that are used in the medical science world, environmental monitoring projects, and large-scale power generation projects, which further boost the growth outlook of the flexible generators market. A number of potential application areas are being explored in an effort to evaluate the practical market value of flexible generators – some of the top exciting areas of application include LEDs, biochemical motion monitoring devices, and powering sensors.

Moreover, in the wake of critically rising need for switching to environmentally sustainable, and more convenient sources of energy, a greater number of research studies are coming up with investigations around this clean, green, efficient, and portable energy source. Renewable sources of energy, including solar, also play a crucial role in directing research. Fabrication of hybrid energy cells through potential integration of TENGs with other types of power generators is also emerging as an area of interest among research communities. The ultimate objective remains enhanced output performance that would efficiently meet a variety of functional requirements in real world.

Flexible Power Generators Find Significant Application in Wireless Sensors on Account of their Exceptional Functional Attributes

Flexible generators are expected to rise as a preferred power generation source owing to their solid electrical conductivity, superior inherent flexibility, and higher mechanical stability when compared to convention equivalent sources. Exceptional advantages of TENGs like simpler production, lower costs, lighter weight, sizeable output power, and most importantly the high conversion efficiency will continue to contribute toward the growth of the flexible generators market. Wireless sensors are emerging as a remunerative potential application area for flexible generators market players as the wireless technology continues to take the world by storm. Burgeoning adoption of next-generation technologies such as Internet of Things (IoT), Augmented Reality (AR), and Virtual Reality (VR) remains a strong force behind the increasing interest in wireless sensors, which is also driving market growth.

Addressing Key Challenges Associated with TENG

The fundamental mechanism of contact electrification involved in the mechanism of action of triboelectric nanogenerators is yet to be clarified. High susceptibility of the triboelectric materials to mechanical wear and tear is also a challenge that remains unresolved as of this point in time. Longstanding challenges that continue to face manufacturers of flexible generators out to be effectively addressed is the world looks up to large-scale applications of TENGs. While selection of advanced materials such as graphene, carbon nanotube, and nano-Ag ink is being looked at as a route to improved output power of TENGs, a lot has to be worked upon to achieve desired durability, and stability of the output.

Materials researchers have also been working on possibilities with the various materials like silicone, and fibre, which may bring in more stability, and endurance. Several research studies also focus on dealing with higher proneness of TENGs to mechanical wear amid a range of external environmental factors, which is leading to the development of potentially effective packaging technologies that would protect flexible generators in the long run.

Asian Economies Attract Investors on Account of Cost-effective Production, and Labour

While the US, Germany, and Japan remain the frontrunners in the flexible power generation landscape, Asian markets hold the promise to holding the future of TENGs. The three top countries continue to form the core of R&D on the back of superior research facilities, supportive infrastructure, funding, and favourable regulatory framework. However, limited manufacturing resources continue to challenge the three. On the other side, fast-developing economies such as India, Brazil, and China will remain crucial as they have been witnessing an exploding market for wearable devices over the recent past. Surging demand for compact power supply devices across thriving Asian markets further supports the growth of the flexible generators market in Asia Pacific. The region is also expected to provide a strong base to market build-up as it houses the maximum number of companies partaking in consumer electronics powered by TENGs. Leveraging the cheaper labour costs, and reduced overall manufacturing costs, especially in countries like China, South Korea, and Vietnam, companies from the US, Germany, and Japan have been opting for contract manufacturing, and licensing deals with these Asian economies.

Notable Developments in Flexible Power Generators Space

• Recently, a team of researchers from South Korea created a high-performance TENG, precisely an inertia-driven TENG (I-TENG), targeting its usage in a self-powering cardiac pacemaker. Functioning through the combined energy of gravity, and body motion, this coin battery-sized generator has a layered structure. The materials that have been used include gold, copper, and two polymer-based triboelectric materials. This study points to a new realm unlocking opportunities for TENGs in self-charging devices potentially employable for clinical application areas, especially those like implantable medical devices capable of self-recharging
• More recently in 2021, some Indian scientists working with the Centre for Nano and Soft Matter Sciences (Bengaluru) have fabricated a TENG that is capable of power generation from different vibrations in surroundings. The generator is transparent, and is targeted for its potential use in novel self-powered devices, and optoelectronics. The team has also been exploring its application potential for biomedical science
• A research team at the Chinese University of Hong Kong (CUHK), Faculty of Engineering, has recently made an attempt to overcome the technical challenges associated with TENGs by an innovatively designed water-tube-based generator (WT-TENG). This flexible generator can harvest energy from low-frequency irregular environmental sources like the waves of water. This development again marks the rise of potential opportunities in the similar area of research, and application.
