Patent Granted for AMAD’s “Wearable Multi-Directional Blast Sensor”–The OmniBlast Air

We are pleased to announce that Advanced Materials and Devices (AMAD) has been granted a patent for the OmniBlast™ Air sensor.  This patent marks a significant milestone in our mission to advance blast measurement and safety technology.

The uniqueness of the OmniBlast™ Air sensor is that it is the first wearable direction-independent blast sensor of its kind, designed to capture blast overpressure events from all directions with high fidelity, utilizing 5 time-synchronized pressure sensors each sampling at 400 kHz.  This compact device, weighing less than 2 ounces and measuring less than 2 cubic inches, brings laboratory-grade accuracy to field applications.

Key Features

  • Compact Design: The sensor’s small size ensures portability and flexibility without sacrificing accuracy.

  • High-Fidelity Measurement: With a pressure range of 0.5 psi to 100 psi with 5 pressure sensors each sampling at 400 kHz (400,000 samples a second), the OmniBlast™ Air provides accurate direction-independent blast sensing and recording

  • Usability: Access and analyze data through both wired (USB-C) and wireless (BLE/Wi-Fi) connections. The OBA+ model is an Internet of Things (IoT) device that directly connects to Wi-Fi networks. Recorded blast event data is automatically uploaded to the cloud for storage and analysis, eliminating the need for user intervention and reducing logistical burden.

  • Durability: Waterproof and rugged, the sensor is designed for challenging environments.

  • Efficiency: A rechargeable battery, and the capacity to record over 5,000 blast events (before needing to offload) make this sensor a reliable tool for extended use.

This achievement underscores AMAD’s dedication to enhancing safety and protection for those exposed to blast overpressure.  With the OmniBlast™ Air, we bring a new level of precision and reliability to blast measurement, setting a new standard for wearable sensor technology.
