Portable Stroke Detection Device Development Case Study

This case study details the development of a portable stroke detection device utilizing microwave-sensing technology. The document outlines the challenges faced by a medical device company based in Sweden, which originated from a research department at Chalmers University. The company aimed to create a lightweight and compact device capable of on-the-go brain scans for early stroke diagnosis. It describes the integration of a customized embedded microwave-sensing solution, developed in collaboration with Keysight, which includes a benchtop network analyzer and a vector network analyzer. The solution is designed to be portable, weighing less than 1 kg, and operates efficiently on battery power. The case study highlights the successful launch of the first microwave-based diagnostic system for stroke detection, emphasizing its capabilities for prehospital brain injury screening. The device's small form factor and rapid diagnostic performance are noted as key features that enhance its usability in emergency medical situations.
