Journal ArticleDOI
Experimental studies of using wireless energy transmission for powering embedded sensor nodes
David Mascareñas,Eric B. Flynn,Michael D. Todd,Timothy G. Overly,Kevin M. Farinholt,Gyuhae Park,Charles R. Farrar +6 more
TL;DR: In this article, a mobile-host based wireless energy transmission system is proposed to provide both power and data interrogation commands to sensor nodes for structural health monitoring (SHM) applications.
Journal ArticleDOI
Development of an Extremely Compact Impedance-Based Wireless Sensing Device
TL;DR: The development of the next generation of an extremely compact, wireless impedance sensor node for use in structural health monitoring (SHM) and piezoelectric active-sensor self-diagnostics and its broader capabilities are demonstrated.
Journal ArticleDOI
Piezoelectric Active-Sensor Diagnostics and Validation Using Instantaneous Baseline Data
TL;DR: The effects of temperature variation on the sensor diagnostic process is examined and an efficient signal processing tool is developed that enables the identification of a sensor validation feature that can be obtained instantaneously without relying on prestored baselines.

Journal ArticleDOI
Development of capacitance-based and impedance-based wireless sensors and sensor nodes for structural health monitoring applications
David Mascareñas,Eric B. Flynn,Michael D. Todd,Timothy G. Overly,Kevin M. Farinholt,Gyuhae Park,Charles R. Farrar +6 more
TL;DR: In this article, a field demonstration of a new and hybrid wireless sensing network paradigm for structural health monitoring (SHM) is presented, where both power and data interrogation commands are conveyed via a mobile agent that is sent to each sensor node to perform individual interrogations, which can alleviate several limitations of traditional sensing networks.
