Research Summary

Prof. Peroulis focuses on reconfigurable electronics for adaptive communications, signal intelligence, and harsh-environment MEMS sensors. He has been a PI/co-PI in over 65 projects funded by government agencies and industry in these areas. He has been a key contributor to numerous filter-centric programs that have resulted in the first widely-tunable (tuning range >3:1) pre-select radio filters with unprecedented quality factors (Q > 1; 000) and power handling (> 10 W) for high frequency applications (1-30 GHz). A wide variety of reconfigurable filters with simultaneously adaptable features including frequency, bandwidth, rejection level, filter order, and group delay have been demonstrated over the past five years. His group has been developing a groundbreaking concept of Field Programmable Filter Arrays (FPFAs). Inspired by FPGAs in digital systems, FPFAs are based on a sea of coupled resonators and multiple ports in order to enable re-utilization of the same adaptive resonators to support diverse needs for dissimilar systems. Arbitrary operational modes and multiple operational channels may be created and reconfigured at will. Besides RF front-end filters, Prof. Peroulis’ team has made significant contributions in high efficiency power amplifiers (2011-2012 awards in the MTT-S International Microwave Symposia Student Design Competitions) and co-designs of reconfigurable RF devices.

Prof. Peroulis has also been working in the fields of wireless MEMS sensors and energy harvesting. His team demonstrated the first wireless battery-free high-temperature MEMS sensors for health monitoring of rotating machinery. These sensors continuously monitor the true temperature of a rotating device to over 300◦C or 550◦C (depending on the design) and wirelessly transmit it to a base station. These sensors are based on well-established silicon processing for low-cost high yield manufacturing. They have demonstrated extremely robust operation for >109 cycles and continuous loading for >3 months without failure. Furthermore, in 2012 his team’s work on energy harvesting won the Outstanding Paper Award by the IEEE Ultrasonics, Ferroelectrics, and Frequency Control Society (Ferroelectrics section). More recently his team has been researching wireless sensors for manufacturing of pharmaceuticals, biotech products and emergency food supplies. These processes are currently highly inefficient due to the lack of fundamental understanding of the underlying physical principles. The envisioned sensors are expected to lead to significant advancements in such manufacturing processes.
