Low Cost Smartband to prevent COVID-19

According to the World Health Organization (WHO) and the Brazilian National Health Surveillance Agency (Anvisa),  one of the main means of contagion in the second wave of contamination by the coronavirus (COVID-19) is the hands.
Every moment, the hands are used to greet people and handle objects, but shortly thereafter, it is common to use  them to touch the face. Such an involuntary action can take all kinds of harmful agents into the body. Hence, this work  aims to present and share the development of a low cost bracelet that helps the user not to touch the face with the hands.  As a result, it is expected to reduce the spread of this virus through this type of contagion. For this, the bracelet monitors the position of the hands and issues an alert when it detects the approach of the hand to the face. Initially, a first prototype  was made to observe local public (state of AlagoasBrazil) interest in the product. The blog of the project reached over   1,000 views in just two days. The sequence of the project was extended in the development of the product so that it can be used by the final public in risky regions. The extremely low cost of the bracelet is capable of helping people from  underdeveloped countries like Brazil, and countries in Africa to stop practicing this harmful habit for their health.   Through government funding, 500 bracelet units are being made for donation to the state of Alagoas, Brazil
