Nowadays, the use of sensors has achieved great importance in various fields. Agriculture, pollution detection, and food safety are just some of the fields that have demanded the use of increasingly precise and accurate sensors. Of all of them, the medical field has paid great attention to the use of sensors in diagnosing and treating diseases. The use of drugs for surgical or therapeutic purposes involves careful attention to the doses administered to the patient. Overdosing a specific drug can lead to organ transplantation and/or malfunctioning of apparatuses and systems. An example is the use of paracetamol as a pain-relieving and antipyretic agent, the improper use of which can lead to liver and kidney failure.
