    Wireless Patch SoC for
    Real-Time Vital Monitoring

Imagine a wireless medical patch that sits discreetly on your skin — continuously collecting real-time data from an implant inside the body, processing it, and sending it wirelessly to your phone. This is more than just convenience; it’s a breakthrough in patient care. For a pioneering medtech company, this vision meant creating wearable video stream capturing in patch form — ultra-compact, power-efficient, and capable of reliable wireless communication in a complex biological environment.
