A Wireless Stent for Coronary Heart Disease
A micron-scale stent with very low power source actuated using a radio frequency signal.
• Challenges: − quantifying the sensitivity of the proposed device and interrogation range− selecting polymer material type, interrogation power levels, frequency of
operation, size, required receiver sensitivity and device identification code length
• Applications:− Replace drug eluting stent – a stent with a drug delivery option− Ureteric stent - kidney stent – usually placed inside the ureter, between the
kidney and the bladder to temporarily relieve obstruction. − Esophagus stent usually used to keep a blocked area open so the patient
can swallow soft food and liquids.
• Presently:− focussing on device structure and coding requirements

Centre for Biomedical EngineeringRF Transceivers • Project: Design of Digital Phased Array Module using RFIC
− A fully integrated digital phased array for both civilian and military applications operating between 2-18 GHz.
− Design and implementation of digital phased array in SiGe and CMOS technologies.
• Challenges:− design of radio frequency circuits on a common substrate: analog-
to-digital converters, digital-to-analog converters, amplifiers, mixers, low noise amplifiers, phased-locked-loops and oscillators
− for such system integration, new design techniques for RF, low power, low voltage, high frequency circuits are needed.
• Applications:− Radars− Electronic surveillance − Wireless devices− Distributed sensors− High performance transceivers
