Can Sensing Be Safe? Designing Privacy-Aware Wireless Systems

Introduction From fitness trackers to smart speakers, mobile sensing has quietly become ubiquitous, embedding itself into our daily lives. These devices are capable of monitoring motion, detecting presence, identifying user activities, and even inferring health conditions, sometimes without any user interaction. As these applications grow and become central to smart environments, a critical question arises: Can sensing systems be designed to be both safe and ethical? While mobile and wearable
