Wireless technology takes the worry out of inaccurate patient reported outcomes 

 (Charlestown, MA) has created a new device that employs wireless technology to measure physiological measurements such as peak expiratory flow or blood sugar levels wirelessly, then integrates the data with an eDiary. The technology also enables subjects to send subjective data such as pain level versus activity level. With eSense, they can wear a small device to record data during the day, then return home and transmit the information to an eDiary that night. The advantage, says PHT, is that clinical trial subjects no longer have to remember scores or times, or worry about transcription errors. 

The technology that makes eSense possible is a low-power wireless design that allows devices within 10 feet of each other to communicate. This also enables eSense to be integrated into tiny, wearable devices that are more convenient. Subjects simply use the device near their eDiary and the data transmits automatically, with date and time stamps for every reading.
