—This paper reports a magnetic sensing device for in-vivo artery pressure monitoring. The device consists of multiple magnets and hall sensors arranged orthogonally on a flexible substrate. The novelty of the device lies in the component plurality and their geometrical configuration, which enhances pressure sensitivity. Several designs involving different number of components have been investigated through Finite Element simulations. The design that incorporates two cross-positioned magnets and sensors exhibited an eight-fold improvement in artery expansion response compared to the traditional single magnet-sensor configuration. In-vitro experiments carried on a surgical latex tube demonstrated a five-fold improvement in pressure sensitivity. Further development of this device will enable continuous monitoring of blood pressure after organ transplantations.
