Ossia is first and foremost a wireless power technology innovator. We design the technology for real wireless power -- without wires, line of sight, or charging pads -- and develop sophisticated and demonstratable prototypes, but we don’t create the end product. We leave that to our licensees. This gives them the most freedom to create a wireless power system that works best for their unique situation.
You might think focusing on technology innovation would make it difficult to test our technology specifications, but thankfully, other companies in the wireless power ecosystem are already very good at product development and execution. By collaborating, we can leverage the best engineers to create working Cota wireless power models to test and draw standards from.
Whenever we’re ready to make an application of our wireless power technology, like the Cota Forever Battery, available for license, we collaborate with companies like Simplexity Product Development, a product design firm with a strong group of engineers.
Relationships like this help us fine tune our technology specifications and give everyone confidence that the technology will work in the real world.
In order to fully vet out our reference documentation and demonstrate how to best implement the Cota Forever Battery technology into a device, Ossia’s radio frequency engineers collaborated with Simplexity’s electrical and mechanical engineers to:
A standard AA battery measures 14mm by 50mm, and the custom circuit board that Simplexity created was 11mm x 40mm. The radio frequency antenna curved along the inside of the AA-battery-shaped cylinder. The case was made from high-resolution SLA printed plastic; SLA (stereolithography) is a form of 3D printing technology. This architecture allows the Cota Forever Battery to scale directly into cost-effective, injection-molded housing parts without a major redesign.
The metal end caps of the Forever Battery were created with a small tab with a spring force that interfaces with the plating on the edges of the printed circuit assembly (PCA). For the initial prototypes, the edges of the board were plated with a thick layer to allow for it to be removed and replaced without rubbing away the contact material. This allows for ease of assembly and a robust contact after assembly.
Transforming how power is delivered across the world takes a coordinated group effort. That’s why we encourage collaboration and communication throughout the wireless power ecosystem, by connecting innovators, designers, manufacturers, and service providers and encouraging idea-sharing, troubleshooting, and developing wireless power solutions together. The Cota Forever Battery is just the beginning.
