4. 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

5. RF 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

6. 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 • People: MostafaRahimi , OmidKavehei, Dr Said Al-Sarawi, Prof Derek Abbott, and Dr NicolangeloIannella
