Sweat ID

SweatID is a Life Sciences startup based upon a wearable device for health and fitness applications. The SweatID system uses a fabric-based sensor to monitor the wearer’s hydration in real-time, enabling continuous monitoring of sweat biomarkers on the skin’s surface.

Prior to engaging Porticos, the SweatID team had created a promising proof of concept prototype and was looking for a Product Engineering partner to help bring it to the next level. SweatID chose Porticos to develop their technology into a fully functional wearable device.


Porticos faced a number of challenges, beginning with the user experience. Since this was a product to be worn, it was important to make sure the form factor and user interface were pleasant, and that the final product would be comfortable. At the same time, the device needed to integrate a replaceable sweat sensor that would be protected from water ingress and corrosion.

To address these issues, Porticos started by generating concept art and worked closely with SweatID to move forward with a design that best aligned with the product vision. Porticos then fabricated high-fidelity prototype units, complete with an assembly method, alignment jig, and work instructions for SweatID employees.

These prototype units were able to achieve all the requirements of the project. Corrosion-resistant materials were used and an adhesive backing provides a water-tight seal for device protection. The User Interface includes a recessed graphic nameplate that is flexible, allowing for a button press through a “living hinge” in the plastic housing. Finally, the overlay remains transparent in select areas to ensure the visibility of an indicator light.


The final result of the product development effort was the successful implementation of our client’s vision, and delivery of a fully-functional unit for field testing.
