Characteristics of magnetic sensor with assembly errors in a rotary recording system

A New Diagnostic Technique to Detect Early Migration of Joint Prostheses

“…No instrumented prosthesis has been designed for the TEA that can monitor the prostheses performance to our knowledge to give feedback. A magnetic field measuring system, which has been used broadly for positioning sensing in automation industries and for contactless movement in harsh environment [25], is another technique that can potentially be used in a prosthesis for motion or loosening detection. Magnetic sensor can be divided into two types based upon their excitation (coils and magnets).…”

“…Magnetic sensor can be divided into two types based upon their excitation (coils and magnets). The sensors are fabricated in way to output orthogonal signal with respect to magnetic field [25,26]. Recent advancement in magnetic sensor design has worked on providing low power, small size, and high-resolution sensors to estimate the intensity and orientation of a magnetic field [26].…”
