SPKL develops a low‑cost, wearable optical device that continuously measures quantitative blood flow and perfusion in tissue. By providing non‑invasive, plug‑and‑measure monitoring of pulsatile blood flow from the brain, the technology aims to enable rapid stroke triage in the field and reduce treatment delays. The platform’s flexible probes can also be adapted for broader cardio and neuro‑vascular monitoring applications.

Problem
Stroke patients often experience critical delays because they must travel to hospitals equipped with imaging devices to confirm stroke type before treatment can begin. This time lag can lead to worsening outcomes, especially in regions lacking immediate access to advanced imaging.
Solution
SPKL offers a low‑cost, wearable optical device that continuously measures pulsatile blood flow in tissue using Integrated Diffuse Speckle Contrast Spectroscopy (IDSCS). The system illuminates the skin with safe near‑infrared light and analyzes the reflected speckle fluctuations to quantify perfusion in real time. Its plug‑and‑measure design requires minimal training, allowing first responders or clinicians to triage stroke patients in the field and identify those needing urgent transport. Flexible probe configurations enable the same technology to be applied to cardiac and other neuro‑vascular monitoring scenarios, providing quantitative perfusion data wherever needed.
Target Audience
Primary customers are emergency medical services, stroke triage teams, and hospitals seeking rapid, quantitative perfusion assessment for patients before hospital admission.
