Wearable Biofeedback Device Case Study

A design team working on an innovative biofeedback product approached JN White® for assistance. The team was working with another vendor who was unable to be an effective partner. Although this vendor was occasionally able to produce acceptable product, they did not provide consistency, nor the support required to keep pace with the customer’s iterative design process. JN White® began working with the team and quickly helped to move the membrane switch project into initial concepts. They continue to support the project with additional engineering, production and assembly support as the product moves into full-scale launch in the near future.


Prior to working with JN White®, the team developing the NIGHTWATCH® product were working with an overseas vendor. The project required many prototypes and modifications to accommodate the various use cases and environmental factors under consideration. With the prior supplier, the engineering team faced language difficulties, shipping challenges that impacted response time and, at times, poor components. Given the complexities of developing and launching this product, the team at NRGXP began searching for a better partner.

How JN White® Helped

The team at JN White® quickly came up to speed on the project and, with the elimination of the language barriers, helped to move the project forward quickly. The JN White® Engineering team started with original customer drawing/concept and further refined the concept to incorporate the following requirements:

  • Engineered with curved metal panel in mind due to where the panel will be used (e.g. in collar/bridle)
  • Required that the panel be soldered onto a rigid panel with connector for support and durability (won’t pop off)
  • Incorporated an LED for switch
  • Resulted in a hybrid flex circuit utilizing copperflex paired with VHB as a diffusor which also protects the panel from debris and humidity

In addition, the team utilized JN White®’s digital capabilities to produce variable data/sequencing information on each component for tracking.


JN White® was able to assist the customer in engineering and producing a product domestically that met all the specific requirements. In addition, JN White® is providing value-added custom assembly support for the charging cables/docs. The partnership will continue to evolve as the customer moves through a soft launch into a full production launch in the next 12-18 months.

"Very pleased with your team's response to our need during the COVID-19 crisis."
Lisa L., Medical Device
"JN White has been exceptional in working with our company in order to develop the look and feel of our new MRI patient worn transmitter. We had originally worked with a prior manufacturer for an earlier version of this product with much less desirable results. JN White delivered a clean professional product at a very reasonable price on time!"
