Inspiration

As women, we’ve all felt that unspoken fear—the vulnerability in public spaces, the risk in private ones. We asked: Why does safety tech still feel like an afterthought? TagHer was born from the urgent need to make safety proactive, intelligent, and wearable. We envisioned a future where protection is not just reactive, but built into what we wear—with purpose, power, and precision.

About the product

TagHer is a breakthrough in wearable safety tech—an intelligent, invisible bra tag designed to detect forceful or unauthorized removal and instantly trigger a panic mode or SOS alert to trusted contacts. Built to seamlessly integrate with daily wear, TagHer empowers women with silent protection in vulnerable situations—without compromising comfort or discretion. This isn’t just a product; it’s a movement toward redefining personal safety through innovation.

How we built it

We prototyped TagHer using: Force and stretch sensors integrated into a compact module A microcontroller (ESP32) for real-time signal processing and connectivity Bluetooth and GPS to enable discreet alert transmission A connected mobile app interface for SOS customization, contacts, and system control We focused on making it ultra-lightweight, discreet, and resilient, iterating through multiple circuit and fabric designs for maximum integration.

Challenges we ran into

Making the device comfortable and discreet without compromising functionality Ensuring high-accuracy detection of actual force events vs. normal wear Designing a low-latency alert system that works reliably across environments Managing power efficiency in a small form factor Navigating the sensitive balance between tech and body-conscious design

Accomplishments that we're proud of

Successfully prototyped a working detection mechanism for forceful removal Built a seamless alert pipeline from sensor to mobile SOS Created a wearable form factor that's actually realistic for long-term use Sparked meaningful conversations around women’s safety and wearable rights This wasn’t just building a product—it was building hope into hardware.

What we learned

Building TagHer taught us that true innovation lies at the intersection of empathy and technology. We learned how to engineer with sensitivity—balancing hardware precision with the lived realities of women’s safety. We deepened our understanding of:

Sensor dynamics and biomechanics to distinguish real threats from normal motion The critical role of UX/UI in safety tech—especially when lives may depend on intuitive design Data responsibility and the ethical considerations of wearable surveillance The importance of iterative prototyping, where each design flaw brought us closer to a solution Most importantly, we learned that tech can do more than connect—it can protect, empower, and advocate.

What's next for Tag-her

We're just getting started. Next, we plan to: Integrate AI-based movement pattern recognition for smarter threat detection Add tamper-detection and fail-safe triggers Conduct real-world user testing and co-design with women Explore patent and mass-manufacturing feasibility Partner with brands to bring TagHer to the market as a safety standard We believe the future of women’s safety is invisible, intelligent, and always on. With TagHer, we’re not just innovating—we’re reclaiming power.

What it does

Detects forceful or unauthorized removal of a bra in real-time Instantly triggers a panic mode or SOS alert to emergency contacts Operates silently and discreetly Designed for comfort, wearability, and uninterrupted protection This is not just a sensor—it’s a guardian, woven into a woman’s most personal space.
