Convenience offered by and consumer preference for the wireless connectivity

Currently, wireless connectivity technologies are being adopted at a high rate. The user wants to get rid of the wired connectivity because of its complexity. Nowadays, consumers expect robust wireless services everywhere including smartphones, notebooks, MP3 players, and digital cameras. Wireless connectivity offers users the freedom of mobility, quick and easy accordance, and handy operations which is why the wireless charging technology is highly deployed in consumer electronics such as smartphones, tablets, and wearable devices. This increasing “go-wireless” tendency of consumers is driving the market for the wireless power transmission technology. Many companies are providing wireless charging-enabled devices that are user friendly, cost effective, and has lifespan of 10 to 15 years. This results into the increasing demand for these devices in the market.

Impact of uncertified and non-standardized products on the industry coherence leads to poor user experience

The wireless power transmission technology has become crucially important nowadays due to its successful implementation into consumer electronic products. Thus, to fulfil the increasing demand, various players, including start-up companies along with their innovative ideas, are entering the market to offer the wireless power transmission technology. This increases competitive pressures among the suppliers of wireless power transmission technology-based products. It is challenging for the Wireless Power Consortium (WPC) and Airfuel Alliance to bring small- and mid-sized suppliers of wireless charging products under their umbrella. Asto gain the competitive advantage, some manufacturers are launching the non-standardized and uncertified products (Qi/Rezence), at a lower cost compared to the standardized and certified products. However, the quality of these non-standardized and non-certified products is not guaranteed, and safety issue is also the main concern in these products Thus, the introduction of such uncertified products hinders the growth of the market for wireless power transmission technology.

Wireless power transmission in robotics (drones)

The wireless power transmission technology has been used for the research and development of mini and micro robots for wireless power transfer. Several research programs pertaining to wireless powered-drones are taking place. A transmitting coil is expected to transmit power at a higher frequency, which would be received by the receiver in robots. Imperial College of London has successfully demonstrated the wireless-powered drone which is likely to operate above five inch of wireless power transmitter. ZiiEnergy, Inc. (U.S.) developing the wireless drone receiver which works on Open Dots Alliance (ODA) standards and can deliver 45 watts of power to drones.

Tradeoff between transmission range, efficiency, and safety of the wireless power system

The wireless power transmission technology is witnessing high growth in consumer electronics applications. It can charge various devices such as smartphones, tablets, and smartwatches. However, the wireless power transmission technology currently faces some limitations. The transmission range of wireless power transmission through electromagnetic induction and or by magnetic resonance technique is limited. This limitation of the range poses a serious challenge for the manufacturers. The efficiency of the power is inversely proportional to the distance between the transmitter and receiver. Safety issue is also the main concern for the wireless transmission market as strong electromagnetic fields may harm the biological environment.
