A CMOS SoC for Wireless Ultrasonic Power/Data Transfer and SHM Measurements on Structures
Xinyao Tang, Soumyajit Mandal, Tayfun Ozdemir
This paper describes a highly-integrated CMOS system-on-chip (SoC) for active structural health monitoring (SHM). The chip integrates ultrasonic power and bidirectional half-duplex…
High-Sensitivity Electric Potential Sensors for Non-Contact Monitoring of Physiological Signals
Xinyao Tang, Wangbo Chen, Soumyajit Mandal +2
The paper describes highly-sensitive passive electric potential sensors (EPS) for non-contact detection of multiple biophysical signals, including electrocardiogram (ECG), respirat…
Digital Communication using Synchronized Hyperchaotic Maps
Xinyao Tang, Soumyajit Mandal
This paper describes the analysis and practical implementation of synchronized hyperchaotic maps for private communication of digital data. The data is transmitted using chaotic ma…
A Programmable CMOS Transceiver for Structural Health Monitoring
Xinyao Tang, Haixiang Zhao, Soumyajit Mandal
We describe a highly-integrated CMOS transceiver for active structural health monitoring (SHM). The chip actuates piezoelectric transducers and also senses ultrasound waves receive…
