Dog Repeller Smart Watch 2021

1. Motivation
Dogs are beloved pets for many people, but not everyone feels comfortable around them. Some fear dogs that bark or run toward them, while others suffer from allergies to dog fur. Additionally, incidents of children or elderly people being attacked by aggressive dogs have been reported in the news, raising concerns for safety during activities like neighborhood walks. While it’s important to protect animals, the needs of those who wish to keep a safe distance from dogs should also be respected. Inspired by mosquito repellent wristbands or necklaces, this device aims to provide a wearable solution to safely deter dogs.

2. Description
a. Summary
This device is a wearable wristband that emits high-frequency sounds that only dogs can hear and dislike, without causing harm to them. Similar to mosquito repellents, the sound covers a specific range to deter dogs from approaching. It provides peace of mind for those who are uncomfortable around dogs, allowing them to walk or exercise without fear.

b. Principle and Originality
Scientific studies show that dogs can hear high-frequency sounds inaudible to humans and find them unpleasant. By carefully adjusting the volume and frequency to cover a safe range, this device ensures dogs are kept at a comfortable distance without harm. Its compact design as a wristband or necklace makes it portable and user-friendly. As such a device has not been developed before, it is highly original.

3. Results (Expected Benefits)
This device offers a safe way for people with allergies or fear of dogs to keep them at a distance without conflict with dog owners. By wearing it, users can feel more secure during walks and coexist peacefully with neighbors who own dogs, fostering better community relationships.
