Millions of patients worldwide suffer from chronic heart failure. Due to the recurring nature of the disease, long-term care and monitoring are an essential part of treatment. Current monitoring devices have attempted to solve the issue, but have failed to reduce rehospitalization rates due to their high costs, intrusive designs, and lack of mass accessibility.

Chronic heart failure, also known as congestive heart failure, is the ongoing inability of the heart to circulate enough blood throughout the body, resulting in an insufficient supply of oxygen. While the causes of the disease may vary, some of the most common risk factors include old age,being overweight, diabetes and high blood pressure.
