What Is the Proxxi Band by Grace Technologies and How Does It Improve Electrical Safety?
The Proxxi Band by Grace Technologies is a wearable voltage detection device designed to enhance electrical safety for personnel working near energized equipment. It provides real-time alerts to help prevent electrocution and reduce workplace incidents.

How It Works
The Proxxi Band continuously senses AC voltage and alerts users when they approach live electrical sources.
- Alerts: Haptic vibration, audible beeps, and LED flashes intensify as proximity increases.
- Detection Range: 110V–500 kV AC (default 480 V).
- User Control: Workers can adjust or mute alerts for specific energized tasks.
- Battery Life: ~30 hours per charge via micro-USB.
The wristband connects via Bluetooth to the Proxxi mobile app and Proxxi Voltage Dashboard, enabling supervisors to view alerts, usage patterns, and safety compliance data
Key Benefits
- Prevent Electrical Catastrophes: Adds an extra safety layer when traditional controls fail.
- Proactive Risk Management: Analytics reveal high-risk zones, teams, or behaviors before incidents occur.
- Boost Worker Confidence: Reinforces a culture of safety and accountability.
- Proxxi Promise: Grace covers up to $100 K of medical deductible if an injury occurs while using the device properly
