The research projects in our lab focus on the integration of MEMS and NEMS for both microelectronic and bio-sensing applications. We also develop new technologies for flexible electrodes that can be used for in vivo monitoring and diagnostics. Our group is strongly involved in industrial projects.

• Polymeric MEMS for medical applications
  
• Properties of nano scale organic layers as diffusion barriers for sub micron interconnects
• Dielectric spectroscopy of molecular and cellular phenotypes
• Cell on chip technology for environmental monitoring
• Integration of nano scale organic layers as gate insulators in field effect transistors
• Construction of on-chip electro-analytical 3-electrode cell for bio-chemical sensing
• Currently our group includes 8 PhD students, 12 MsC students, 1 post doc and 4 research staff.

Major equipment include: electro and electrochemical characterization systems, organic glove box, high vacuum oven and optical detection system for biological signal,

This lab was started in 2004/2005 as Bachelor Project of Computer Engineering Students. In the design part we use ISE Foundation design software of XILINX and ModelSim simulator. Debug part consist of specially designed windows based software monitor and an instructional computer based on XSA-50 board of XESS, called RESA-2.

Course topics include:

• Computer aided hardware design and simulation.
• Design implementation and hardware debug using target FPGA.
• Design of a simple RISC processor on an instructional computer. Acquaintance with basic components of the computer architecture: main memory, main bus, bus protocol.

The advanced DSP lab was donated in 2002 and supported ever since by Texas Instruments. The lab provides an advanced undergraduate senior-year course in the "Signal Processing track". It is based on TI's TMS320UC5402 DSP boards, and features six DSP experiments aimed at demonstrating and exploring both theoretical and practical considerations in real-time implementation of DSP algorithms. The experiments include basic introductory functions, as well as more elaborate tasks such as real-time spectral analysis, Dual-Tone-Multiple-Frequency (DTMF) extraction, FIR and IIR filtering and adaptive notch filtering.

The advanced lab for projects and research in signal processing was donated in 2002 and supported ever since by Texas Instruments. The main activity in the lab consists of senior-year projects in DSP, as well as of a limited number of M.Sc. research projects. The lab is based on a large variety of DSP boards, tailored for the variety of applications addressed by the various projects, such as array-processing of audio signals, processing of physiological signals, of video signals, radar, sonar, source localization, etc., as well as infrastructure projects aimed at the development of generic tools for future use in other projects in the lab.

The solar energy laboratory is located in the Wolfson building on the 4^th floor, room 402 and on the rooftop above the floor.

Research on solar energy, in particular, photovoltaic energy is performed in the laboratory and on the rooftop. Photovoltaic arrays may be deployed on the roof exposed to sun rays and the output is conducted to the room via cables for measurements, storing and data processing. In the solar energy laboratory we investigate the performance of single cells, modules and arrays, we calculate the electrical parameters, the effect of shading on cells and arrays and perform optimal design of solar thermal and photovoltaic   fields. Instruments for measuring the solar irradiance and the I-V characteristics of cells and arrays were also developed in the laboratory.

• The lab serves graduate MSc and PhD research students who study signal processing in various application, such as precipitation estimation using cellular network data, detection of neurological activity in the brain, inference of cosmological parameters from measurements of the cosmic microwave background radiation, basic research in estimation theory in the field of lower bounds on the estimation error analysis, and research in communication theory in the field of dynamic spectrum management in interference channels.
• The lab includes 7 fixed workstations, and two operational computer systems, which collect and hold real time data of cellular network activity measurements, used to estimate meteorological conditions.
