Researchers now have a possible solution for the one in three adults who fail to take their medicines as prescribed by their doctors, as well as for everyone else who occasionally forgets: a sensor necklace that records the exact time and date when specially-designed pills are swallowed, and reminds the user if any doses are being missed.
Forgetfulness is a huge problem, especially among the elderly, but so is taking the medication at the wrong time, stopping too early or taking the wrong dose, said Maysam Ghovanloo, assistant professor in the Georgia Institute of Technologys School of Electrical and Computer Engineering. Studies show that drug noncompliance costs the country billions of dollars each year as a result of re-hospitalization, complications, disease progression and even death.
Ghovanloo and graduate student Xueliang Huo have designed a sensor necklace that records the date and time a pill is swallowed, which they hope will increase drug compliance and decrease unnecessary health care costs. The device could also be used to ensure that subjects in clinical drug trials take the study medications as directed by the research team. The details of the proof-of-concept device were published in the December 2007 issue of the IEEE Sensors Journal.
The necklace, called MagneTrace, contains an array of magnetic sensors that could be used to detect when specially-designed medication containing a tiny magnet passes through a persons esophagus. And for persons who may not want to wear a necklace, MagneTrace sensors can be incorporated into a patch attached to the chest.
The date and time the user swallowed the pill can be recorded on a handheld wireless device, such as a smartphone, carried on the users body. The information can then be sent to the patients doctor, caregiver or family member over the internet. The device can notify both the patient and the patients doctor if the prescribed dosage is not taken at the proper
