The Quantified Self website provides a current list of many of the self-tracking tools out there.

From the FDA Patient Network website: "You can participate in FDA’s important decisions about the regulation of medical products in many ways. You don’t have to be an expert, and you don’t need lots of time. Find out how you can make your voice heard and help ensure the effectiveness and safety of drugs, devices, and other medical products."

From the California HealthCare Foundation: Wireless communication standards have allowed sensors to develop from traditional forms — those that require the active involvement of the patient in collecting data, transmitting it, or both — to passive forms that do not need patient participation. The most fully passive sensors can provide constant monitoring of a person's vital signs or other measures, and store that data or send it wirelessly to a care team.
