Arterial pulse measurement is a crucial indicator of cardiovascular health and prevailing techniques such as resistive force sensors, capacitive sensors and pulse oximeters possess challenges in wearability, continuous monitoring, and user comfort. In this paper, we present the development of a novel inductive sensor for non-invasive arterial pulse measurement. The proposed sensor incorporates high-permeability magnetic fillers into a flexible silicone based polymeric matrix. The sensor operates on the principle, that the permeability of the material changes in response to mechanical stress and possess high sensitivity. The experimental results revealed that the sensor demonstrates high linearity and sensitivity. The measured heart rate is compared to a standard clinical pulse oximeter (error $< 15\%$). Furthermore, its flexibility and form factor make it suitable for integration into wearable devices for continuous monitoring.
