The Challenge
Working with Remedee Labs, which has patented technology for non-pharmaceutical treatment of chronic pain, we reviewed and critiqued their existing design, with a particular focus on the antenna that is critical for power transfer into the skin. The goal was to improve the RF radiation efficiency and homogeneity of RF fields.
We then redesigned the mm-wave antenna and optimised the design for reduced manufacturing costs, while ensuring high performance and reliable operation. The approach uses millimetre wave RF signals to trigger the natural release of brain endorphins, providing a novel and effective treatment for chronic pain.
The Approach
We carried out a peer-review of the client’s existing technology, which involved a literature survey, electromagnetic simulation, and design calculations. This enabled us to evaluate the efficacy of their current approach.
To enhance performance, we made adjustments to the element spacing and phasing, as well as implemented transmission line impedance matching techniques.
To reduce expenses, we utilised cost-effective mm-wave PCB laminates and strategically placed PCB vias to lower the number of vias needed. Then, to improve the transmission of RF signals into the skin, we integrated a biocompatible radome.
These enhancements ensure that the client’s technology is optimised for efficacy, performance, and cost-effectiveness.

The Outcome
The new product design successfully achieves a tenfold increase in radiated power density whilst also improving field homogeneity.
There is excellent agreement between the design calculations, electromagnetic simulations, and measurements, validating the effectiveness of the design.
Remedee Labs is currently undertaking multiple clinical trials in university hospitals. Initial trials for sufferers of osteoarthritis have yielded positive results. Further results are anticipated for other types of pain, such as fibromyalgia.
