NuCurrent represents the new gold standard for high-efficiency wireless power antennas.
NuCurrent works with you to custom-design, fabricate and integrate the optimal wireless power antennas for your specific application.
Compared to standard antennas, NuCurrent antennas offer higher efficiency, smaller sizes, longer battery life, greater distances, increased alignment flexibility, lower heating and direct integration with your circuit.
The benefits derived from NuCurrent antennas are dependent on the frequency at which the antennas operate. Two of the common frequencies of operation are ~150 KHz (low frequency) and 6.78 MHz (high frequency), preferred by the Wireless Power Consortium (Qi) and the Alliance for Wireless Power (A4WP), respectively.
Low frequency systems (i.e. Qi compliant) – Low frequency systems are the most common systems on the market today. NuCurrent’s antennas (aka “coils”) are attractive for any low frequency systems that operate with close proximity (~<2 cms) and benefit from durable, scalable and easily integratable coils. At low frequency, NuCurrent typically advises building its coils on FR4 (PCB) or Polyimide (Flex Circuit) substrates, which provides substantial durability, consistency, scalability and integratability.
High frequency systems (i.e. A4WP compliant) – High frequency systems are not yet widely available but offer the potential benefits of higher efficiency, greater power transfer distance, improved orientation flexibility and smaller sizes. NuCurrent’s antennas (aka “resonators”) are the best-in-class resonators for high frequency systems. NuCurrent’s resonators provide the highest Q available, small sizes and competitive pricing due to the implementation of its proprietary designs in conjunction with standard fabrication processes (PCB/Flex/etc.).
Whether you are pursuing low frequency or high frequency systems, NuCurrent is happy to speak with you about our custom antennas and the benefits they offer. Typical turn-around time from NuCurrent’s receipt of specifications to delivery of physical prototypes is about 8 weeks and can be accelerated if necessary.
