Abstract
Monitoring ICP non-invasively is a challenge. A novel method to measure ICP using actuators and sensors has been proposed where the skull is vibrated at high frequencies and the receiving signal is measured at the surface eyelid. A design of experiments approach is used to develop the sensor part of the ICP monitoring device so that gain can be maximized using factors such as area, thickness, electrode, and applied pressure. Statistical analysis showed that thickness has the biggest effect on overall gain. Numerical analysis confirmed these results. In addition, sensor packaging is optimized to minimize dampening of the signal and ensure durability, reliability, and repeatability of the measurements. Optimized parameters are then incorporated into a design, the ICP glasses that allow ease of application and consistency of the measurements. The sensitivity of the sensor was measured to be 0.211mV/V.
