A collaboration of scientists fromآ*Brigham and Womenâ??s Hospital, Massachusetts Institute of Tech**logy, and Draper Laboratory, an engineering firm, have been working on a Wireless system to Power electronic Implants placed within the gastrointestinal (GI) tract. Batteries are currently the only practical option for most implants, but their lifetime is limited and it is difficult to overcome theآ*incompatibility of the mucosal lining with the batteries by encasing them somehow. Moreover, near-field Wireless Power that’s already used to Power some Implants that are very close to the surface, such as cochlear implants, doesn’t work for electronics that would be located deeper Inside the body. The research team has **w published in journal Scientific Reportsآ*on how they were able to create and wirelessy Power an electronic device as it traversed through a pig’s GI tract.
Their Tech**logy relies on a midfield coupling transmission approach, one that uses higher frequencies than near-field tech**logies, successfully beaming e**ugh energy from an external antenna to one Inside the implant to Power a number of sensors, some of which may include gas analyzers, thermometers, and heart rate meters. Additionally, the beamed Power is e**ugh to Energize Implants that can release a drug cargo into its environment. Specifically, they were able to deliverآ*37.5â??خ¼W, 123â??خ¼W, and 173â??خ¼W of Power to the implant, yet while keeping the level of radiation emitted below acceptable safety limits.
