Low-Cost Self-Powered Sensors for Behavioral Monitoring

Principal Investigator Richard Fletcher


In many fields of Science, Medicine, and Business, it is necessary to measure what people are doing, how often they do it, and what objects/products are being used. I designed ultra-low-power data loggers that can record sensor information and can interface to ubiquitous mobile phones. Here are some sample applications of this technology:

(*) Cooking stove use -- Cooking stoves are a important health concern. Temperature data loggers powered by the heat of the stove itself can be used to monitor how often stoves are used as well as usage patterns.

(*) Medication compliance -- We can measure how often certain medication is used, such as pill bottles or inhalers.

(*) Water filters/irrigation -- By connectiing the data logger device to a valve, we can monitor water usage for drinking or irrigation.
