Abstract
A simplified micro-magnetic based sensor and a system built with it for detecting or measuring acceleration, speed, position, placement, tilt, and vibration are disclosed for a reduced product size, simplified manufacturing process, and reduced product cost. Both simplified micro-magnetic sensor and simplified micro-magnetic sensor system include a primary micro inductor and a secondary micro inductor coupled with a micro magnetically permeable dynamic medium element that is small, simple and low cost to manufacture.
