Embrace is a wearable device designed to enhance communication and improve safety for individuals during earthquakes. Utilizing LoRa technology, it enables real-time data sharing and status signaling, aiming to improve rescue operations and reducing the risk of loss of life in disaster scenarios, while decreassing stress in affected individuals.
The need for Embrace was identified due to earthquakes severely disrupting traditional communication systems, leaving individuals isolated and unable to relay critical information about their safety and whereabouts. In the chaos following seismic events, especially in vulnerable communities, this lack of communication exacerbates stress, hinders emergency response efforts, and delays rescue operations.
Utilizing LoRa technology for long-range, low-energy data transmission, Embrace allows individuals to share vital information about their well-being and location when traditional communication systems fail. This smart bracelet, part of a network with strategically placed base devices, is affordable and user-friendly.
With the ability to penetrate obstacles and operate in unlicensed bands, it ensures connectivity up to 10 kilometers. Strategically placed base devices, acting as communication hubs, relay information via satellite, eliminating the need for heavy satellite tech in each bracelet. This efficient system enhances communication reliability and coverage in emergency scenarios.
Activated by seismic activity, it allows wearers to communicate their status with a multifunctional button, indicating safety (green light), need for assistance (orange light), or urgent help (red light). It also collects and sends vital data, including location, heartbeat, and temperature, to designated contacts. An LED screen displays incoming messages, ensuring wearers stay informed and can respond effectively.
The Embrace bracelet utilizes silicone, blending soft and hard elements for adjustability and comfort across various wrist sizes. Silicone’s biocompatibility ensures it’s safe for prolonged wear without irritation, while its durability protects against environmental stressors. The design includes an adjustable gap for easy resizing, offering a snug fit. Available in discreet skin tones and featuring optional stainless steel rims or hidden, bendable wire edges, the bracelet combines practicality with wearer comfort, eliminating sharp edges for a seamless experience.
The Embrace prototype began with designing a mould in Fusion 360 and 3D printing it. Early imperfections were corrected by sanding. Using PT Flex 85 silicone required careful mixing and fast injection due to its quick hardening and difficulty filling narrow areas. Despite challenges, a one-piece bracelet was produced, though air bubbles and other flaws prompted further iterations with 3D-printed components and different flexibilities to refine the design.
