Abstract: A novel sensor, intended for use in applications for robots, prosthetics, biomedical devices, or the internet of things, using a ferrous magnetic fluid is presented here. The sensor includes a deformable member containing the magnetic fluid therein and an array of Hall effect sensors to measure the changing magnetic field in the fluid as the deformable member is deformed. The sensor was found to be sensitive to varying applied pressure and is capable of resolving both the location and amplitude of externally applied forces. The range of applications for this novel pressure sensor are broad, ranging from robotics to biomedical devices and the Internet of things. The novel sensor can also be used as an orientation sensor or an accelerometer, torque detector and linear shear forces detector.
