A fundamental requirement in advanced manufacturing facilities is the reliance on networked sensors, which are increasingly designed as e-Work networks with sensor collaboration. Recently, wireless microsensor network (WSN) systems have been developed and are about to gain widespread use as technology and reliability improve and prices drop. Especially, the densely distributed WSNs can signific...

A novel ball bond process optimization method based on a thermal signal from an integrated aluminum microsensor is reported. The in-situ temperature during the ball bonding is measured and analyzed. The ultrasonic period shows distinct features corresponding to the scrubbing of the ball on the pad and the intermetallic bond growth, and the ball deformation by ultrasonic softening. A peak of the...

Users desire microsensors that support reconnaissance, surveillance and target acquisition (RSTA) operations. Typically, the communications bandwidth on these microsensors limits the amount of data that can be transmitted. Therefore, much of the signal processing must be performed within the aggressive size, power, and weight constraints of the microsensor. Furthermore, these microsensors need ...

works have gained importance in a wide spectrum of civil and military applications.1 Advances in MEMS (microelectromechanical systems) technology, combined with low-power, low-cost digital signal processors (DSPs) and radio frequency (RF) circuits have resulted in the feasibility of inexpensive and wireless microsensor networks. A distributed, self-configuring network of adaptive sensors has si...
