Intro to Piezoelectric BAW Resonator Modeling

September 25, 2013

If you are using a cell phone, GPS, Bluetooth, or WiFi, chances are that they all have BAW resonators working inside them. All wireless electronic equipment use RF filters to help narrow down the frequency range they should operate within. With thousands of devices working within closely-packed radio frequencies, it is becoming increasingly important to design filters that would be able to reduce interference from unwanted frequencies, boost the signal-to-noise ratio, and lower insertion loss. Doing so may lead to […]

MEMS Energy Harvester for Reusing Waste Heat

September 24, 2013

Today we welcome another guest post from Kyle Koppenhoefer of AltaSim Technologies, a COMSOL Certified Consultant. In this entry he will discuss modeling MEMS energy harvesting devices. During our recent webinar with COMSOL on thermal-structure interaction modeling, we at AltaSim Technologies demonstrated modeling of a MEMS energy harvester that scavenges waste heat. Examples of sources for waste heat range from microprocessor chips, to internal combustion engines, to chemical processing plants. If the waste heat generated from these cases could be […]
