Modeling The Torque Of Ferrite Nano-Particles As A Ferrofluid Suspended In Liquid To Determine The Electromagnetic Response To Angular Displacement, Jackson Tyler Brennecke
Modeling The Torque Of Ferrite Nano-Particles As A Ferrofluid Suspended In Liquid To Determine The Electromagnetic Response To Angular Displacement, Jackson Tyler Brennecke
Masters Theses
Inertial sensing is an important part of engineering and technology, especially for determining spatial orientation. Most modern inertial sensing units rely on MicroElectroMechanical systems (MEMS) style gyroscopic sensors to determine angular acceleration. This research investigates a novel gyroscopic sensing technology that uses mechanical precision of magnetic nanoparticles, instead of MEMS, to determine inertial measurements. The only other study on this novel technology proposed a scalar set of equations for relating magnetic field and torque magnitude to the magnitude of angular displacement of the sensor. This research develops the theoretical model into a set of full vector equations, so that the …

Masters Theses
Wireless sensor systems are common in applications where harsh environmental conditions or remote locations make it difficult to run wires. Having these sensor systems self-powered is essential as it is difficult for battery replacement. Using solar as an alternative source of energy can be a medium to charge the battery in such scenarios. With an increasing number of portable devices powered by battery; more and more research is focused on low-power design technique. For this thesis, a microcontroller (Texas Instruments MSP432) was used along with a digital sensor (Bosch BME280) to provide temperature, pressure and humidity information, and Wi-Fi module …
