Electronics Design Services

Renfrew Group International has extensive experience in developing and adapting new technologies for product design. Moreover, our work involves electronics and technology development embedded in the working mechanism or user interface. Additionally, we create systems based on scientific theory and fundamental principles, often modifying materials and production processes.

As an electronics design services company, we devise electronic systems exploiting new technologies and create prototypes, either as simulations or hands-on products. Furthermore, when no off-the-shelf solution exists for a problem, we design and develop new hardware to address the core need before finalizing the product.

We excel in developing embedded software using applications like Lab-view, supporting research projects with computer control and data acquisition. Moreover, we have a proven track record in designing fully integrated consumer products. Notably, our recent projects included custom sensors, actuators, microheaters, vaporizers, and special optronics. Additionally, we can develop technology from scratch if needed.

It’s worth mentioning that we’ve contributed to a wealth of valuable intellectual property across various commercialized technology sectors.

Lastly, it’s important to note that Renfrew Group International is accredited to ISO:13485:2016 and ISO:9001:2015, underscoring our commitment to quality and excellence.
