Evren Technologies Internship

Cut electrode-pad fabrication time 85% and built ear-worn bioelectronic devices from prototype to assembly.

As an engineering intern at Evren Technologies, a clinical-stage medical device startup in Gainesville, I built complete ear-worn bioelectronic devices for the Phoenix, an FDA Breakthrough-designated wearable that treats PTSD through vagus nerve stimulation, from prototype through assembly. I designed injection-molded components in Onshape, validated fit and manufacturability with 3D-printed prototypes, and applied design-for-manufacturing, quality checks, and troubleshooting throughout.

The Phoenix

Evren Technologies is a clinical-stage medical device startup in Gainesville building the Phoenix, an FDA Breakthrough-designated wearable that treats PTSD through transcutaneous auricular vagus nerve stimulation (taVNS). The device sits in the ear and delivers gentle electrical stimulation, so every component that touches skin has to be precise, comfortable, repeatable, and manufacturable at scale.

Building the devices

I built complete ear-worn bioelectronic devices from prototype through assembly, applying design-for-manufacturing, quality checks, and troubleshooting at each step.

I designed the injection-molded components in Onshape and validated their fit and manufacturability with 3D-printed prototypes, which kept iteration fast and moved parts from prototype into production.

Cutting fabrication time by 85%

I implemented stamp-press tooling and standardized the electrode-pad fabrication process, cutting pad-cutting time by 85% and improving repeatability across builds.
