Background

Digital wellness wearables have the capability to collect real-time data that reveal the physical and chemical properties of the body to evaluate vital signs of health. These advancements in the development of wearable sensors are helping millions detect and manage chronic health conditions and avoid serious illness on devices small enough to be worn conveniently on the body.

Additive manufacturing processes, particularly stereolithography (SLA)-based printing, have recently been shown to overcome limitations of current fabrication methods by reducing time and cost for manufacturing while expanding the design capacity for novel device architectures with 3D designs (vs. traditional 2D layouts). As a result, an emerging class of wearable devices integrates microfluidic lab-on-chip designs with low-modulus materials, colorimetric assays, and electrochemical
