Design and Analysis of a Sample-and-Hold CMOS Electrochemical Sensor for Aptamer-based Therapeutic Drug Monitoring
Jun-Chau Chien, Sam W. Baker, H. Tom Soh +1
In this paper, we present the design and the analysis of an electrochemical circuit for measuring the concentrations of therapeutic drugs using structure-switching aptamers. Aptame…
Design of Large Effective Apertures for Millimeter Wave Systems using a Sparse Array of Subarrays
Anant Gupta, Upamanyu Madhow, Amin Arbabian +1
We investigate synthesis of a large effective aperture using a sparse array of subarrays. We employ a multi-objective optimization framework for placement of subarrays within a pre…
In Vivo Wireless Sensors for Gut Microbiome Redox Monitoring
Spyridon Baltsavias, Will Van Treuren, Marcus J. Weber +4
A perturbed gut microbiome has recently been linked with multiple disease processes, yet researchers currently lack tools that can provide in vivo, quantitative, and real-time insi…
A Time-of-Flight Imaging System Based on Resonant Photoelastic Modulation
Okan Atalar, Raphaël Van Laer, Christopher J. Sarabalis +2
A time-of-flight (ToF) imaging system is proposed and its working principle demonstrated. To realize this system, a new device, a free-space optical mixer, is designed and fabricat…
Communication with Crystal-Free Radios
Dor Shaviv, Ayfer Özgür, Amin Arbabian
We consider a communication channel where there is no common clock between the transmitter and the receiver. This is motivated by the recent interest in building system-on-chip rad…
Exploiting Spatial Degrees of Freedom for High Data Rate Ultrasound Communication with Implantable Devices
Max L. Wang, Amin Arbabian
We propose and demonstrate an ultrasonic communication link using spatial degrees of freedom to increase data rates for deeply implantable medical devices. Low attenuation and mill…
