无线电力传输(WPT)服务

As more communication is provided wirelessly, the applications and the devices they operate within still need to be truly portable, primarily due to the power requirement limitations and the ongoing need to regularly connect them to a wired AC outlet to recharge them.

Wireless power transmission: Enabling your innovation 

Wireless Power Transmission, or WPT, is the transmission of electrical 能源 到没有电线的设备. WPT technology is useful to power electrical devices where interconnecting wires are inconvenient, 危险, 甚至不可能, 因此, can be used to eliminate the use of cables and batteries, 从而增加了流动性, 方便, and safety of any electronic device for all of its users.

WPT technology has been around for many years. 仍然, it is only recently that the technology has improved and miniaturized to the point where it can be embedded into the smallest devices. 与全球倡议提供更多 电动汽车 comes a need for more convenient ways of charging these vehicles – aka Wireless power transmission.

Wireless power transmission techniques mainly fall into two categories, near field and far field.

Near-field wireless power transmission (WPT) technique

Inductive coupling is the most widely used wireless technology in near-field applications; its applications include charging handheld devices like 手机 电动牙刷， 射频识别标签, 感应烹饪, and wirelessly charging or continuous wireless power transmission in implantable 医疗设备 like artificial cardiac pacemakers or 电动汽车.

Far-field wireless power transmission (WPT) technique

在远场长, 距离或辐射技术, power is transferred by beams of electromagnetic radiation, like microwaves or laser beams; its applications include solar power satellites and wireless-powered drone aircraft.

Compliance requirements for wireless power transmission

An important issue with all wireless power transmission techniques and their associated systems is limiting the exposure of people and other living things to potentially injurious 电磁场.

Stray RF 能源 is limited by regulation worldwide. It requires measurement and assessment of the Specific Absorption Rate (SAR) and Power Density of the RF field to maintain the limits on such phenomena. These ISM frequencies are allocated by the International Telecommunications Union (ITU), 哪一个协调了全球的需求, ensuring that a product designed for one market will technically comply when used in another.
