Abstract	:	A battery-less wireless sensing technology to monitor the cage temperature inbearings was developed. Non-contact measurements are necessary because the bearingcage performs a sliding motion with respect to inner and outer races, and its rotationexcludes direct wiring and the use of slip rings. Four wireless sensing circuit prototypeswere implemented. Three circuits are based on a Colpitts oscillator, a Voltage ControlledOscillator (VCO) and a Meissner oscillator, respectively, and a fourth sensor is based onRadio Frequency Identification (RFID) principles. Radio-frequency (RF) signals are usedto supply the energy to the sensor electronics, so no direct contacts to the sensor circuitsare required. Experimental results on a bearing while it is operating are presented. Thetechniques developed provide a feasible solution for the measurement of the bearing cagetemperature, which can be adapted to monitor the condition of other mechanicalcomponents for which wired circuits are difficult to use..............-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
