Abstract:
A method is provided for internally monitoring pressure of a patient by transmitting an external light source to an implantable microsensor device. The implantable microsensor device has a microlens, a deflectable membrane responsive to a change in pressure of a surrounding environment within the patient, and an array structure disposed between the microlens and the membrane. The array structure includes a first layer that emits a first wavelength of light and a second layer that emits a second wavelength of light responsive to an external light source, where the first and second wavelengths of light are respectively transmissive through the surrounding environment and distinct from one another. Either the array structure or the microlens translates with the membrane in response to the change in pressure of the surrounding environment. The implantable microsensor is compatible with medical imaging devices and does not require an internal or external power supply.
