This E-Team developed a system of products to protect Central California farmworkers from chronic pesticide exposure, which can lead to a wide range of short-term and long-term health effects including cancer, birth defects, and diminished reproductive ability. The team developed two different technologies to combat the problem: a protective suit for the workers and pesticide sensors for their homes. The suit is made from breathable, repellent Tyvek, Teflon and activated charcoal; it consists of overalls with one shoulder strap, an apron over the other shoulder, a hood, a ventilation mask with a carbon filter, gloves, and shoe coverings. The sensors, which incorporate smart dust mote technology to form wireless sensor networks, are designed to detect and record levels of pesticides, providing both an instantaneous alert when pesticides are detected and a long-term record of pesticide exposure, to be used by government agencies like OSHA and EPA in developing case histories of pesticide problems. The team chose the brand name Seguro, which means "safety" in Spanish.
