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




Neuromorphic Engineering• Project: Memristive Devices and Systems: Modelling, Design, and

Applications– A novel non-volatile memory capable of storing analogue and digital data. – research aims at achieving solutions for device modelling and system design.– targeting both nanoelectronic technologies and bio-inspired approaches.– Applications:

• Digital memory (associative memory)• Implementing synaptic plasticity (learning) model

• Project: Analog VLSI Neuromorphic Circuit and Systems: Design and Applications– Design and Implementation of Spiking Neural Networks including neuron and

synapse in VLSI.– The research goal is to Implement learning and memorising circuits using

aVLSI CMOS. – Design and implementation of a neuromorphic pattern recognition system. – Applications:

• Medical Image Recognition, security image recognition, ... • Human-like robot development
