Identified potential hazards in proposed design:

Foreseeable misuses:

Wireless communication is liable to communication based misuse, including but not limited to jamming, spoofing, and repeating. An unsecured connection can expose users to RF-based attacks if signal not protected/encrypted. These types of attacks are very difficult to prevent, but are extremely common and must be accounted for. The device should be a contained system, with as few entry points as possible for tampering with communication. Preventing unauthorized entry to the users computer through RF attacks is also a necessity to protect the users computer.

Changes that may occur during lifetime:

Some issues may arise during the useful life of the product. In this section we identify potential hazards and look at ways to avoid these.

1. Wear and Tear: General wear and tear could impact the useful life of the device. Wear could impact the data collected, make the device uncomfortable to wear, and various electrical or sensor defects that may impede use.
2. Battery wear and tear: Batteries are liable to damage including combustion and flammability, which is potentially hazardous on a wearable device.
3. Overheating: Due to contact with skin, overheating due to electronic load can be hazardous.

Disposal after lifetime:

Electronic devices and battery - based devices may need special disposal to avoid causing fires.
