Vital Signs over Radio


Modulate the vital signs onto multiplexed RF signals, including the heart rate, the respiration rate, the breath effort, and the blood pressure.







Indoor Occupant Counting Based on RF Backscattering

An ultra-low-cost indoor monitoring system for occupant counting based on backscattering from tessellated passive RFID (radio frequency identification) tags on ceiling, walls and floor.









Millimeter Precision Real-Time Indoor Locating

The missing technology for sensor nodes is a small, low-power communication link, in either active radio or passive RFID.

Chemical and Molecular Interface by CMOS

CMOS Biosensors

Integrated chemical and molecular sensors and actuators based on charge-controlled surface electrochemistry by CMOS. Functional sensing-gate coatings for ion, flow, light, stress, molecules, cells, and temperature sensors.



Nanoscale CMOS Systems

Si-based device (logic and memory) and interconnect scaling to the 10nm and 20GHz technology. New structures and materials for devices and interconnect. New circuits (low-VDD, low-power and nonlinear transmission lines) to support further scaling. Scaling of nonvolatile memories to below 1,000nm2 bit area and 4V P/E operations.

Technology CAD for VLSI Design

Device, process and equipment simulation, SPICE compact models, numerical methods and software engineering. Construction of model hierarchy for better analysis and synthesis of the complex design. Technology integration ranging from HDL to partial-differential-equation descriptions.


Si, Ge and C Nanostructure Integration

Parameter extraction of integrated nanotube devices, high frequency characterization and pi-electron transport.
