Abstract The need for braking systems has increased. widely used system is a friction brake. use of brakes problem in maintenance intervals and the risk failure due to heat generation. Research development have carried out. Eddy Current Brake (ECB) an alternative system. ECB that uses eddy currents as source force. Many parameters consider implementing ECB. There been many studies on working Ho...

In this work, a burst eddy current testing technique based on the employment of diamond nitrogen vacancy (NV) center magnetometer with Hahn echo (HE) sequence is demonstrated. With confocal experiment apparatus, HE-based NV attains magnetic sensitivity [Formula: see text] and volume-normalized text], which are ∼five times better than already existing method under same conditions. Based proposed...
