Abstract: Described herein are magnetic sensors (e.g., force sensors) as well as methods of making and using thereof The magnetic sensors can employ a soft magnetic composite (e.g a composite comprising a population of magnetic particles dispersed within an elastomeric resin) paired with a magnetometer. These sensors can overcome many of the traditional shortcomings that have hampered the effectiveness of existing compression sensors in certain applications, including large size, a lack of 3-dimensional sensing capacity, need for sensors to incorporate rigid components, and/or signal quality issues associated with the orientation or deformation of soft composites under compression.
