Transcutaneous Vagus Nerve Stimulation Collar
Introduction to the Project
Needs Statement: Every 40 seconds, someone in the US has a stroke, and every 3 minutes, someone dies of stroke. A leading cause of long-term disability, stroke reduces mobility and sensory abilities throughout the entire body and diminishes quality of life for the patient. The market size for stroke therapy is predicted to hit USD $65.45 billion by 2030. Current acute stroke therapies are either highly invasive and extend recovery times, difficult for practitioners to administer, or ineffective for the long-term improvement of the patient. Stingray aims to change this, and provide hospitals with a stroke therapy device that is noninvasive, simple to administer, and produces long-term solutions for patients.
Value Proposition: Stingray is a stroke rehabilitation product that helps stroke patients receive therapy through a noninvasive and simple to administer device with an effective feedback loop.
Project Description
Stingray utilizes a circuit to send current stimulation to the vagus nerve through a noninvasive neck collar, and is interfaced with a software to drive the feedback loop.
Market Analysis
The markets for both stroke therapy and vagus nerve stimulation devices are growing every year. No currently existing device is able to meet all user needs, driving our team’s motivation to develop Stingray.

User Needs
Potency of Stimulation
Stingray ensures the stroke patient is receiving adequate VNS therapy through a robust feedback loop that is continuously monitoring the effectiveness of the therapy and adjusting accordingly.
Ease of Use for Clinicians
Stingray makes the administration of VNS very simple for clinicians as it eliminates the need to hold the device continuously and does not involve trial and error to find the nerve.
Invasiveness
Stingray is a non-invasive collar that aims to provide adequate VNS from the surface of the neck eliminating the need for surgery and reducing recovery time to zero.
Quality of Reading
To ensure a high quality reading, Stingray is designed to ensure a snug fit around the neck using a flexible collar and an adjustable velcro closure.
