Low-Cost, MEMS Membrane Pressure Sensors

Project by Anwar Farhana Microelectromechanical Systems (MEMS) membranes are widely used in various applications ranging from stiffness tuning to gas pressure sensing. Superior properties such as higher sensitivity of MEMS membranes can be utilized in water-related applications [1,2]. However, lack of reliable processing, testing procedure, and packaging methods leads to electrical and mechanical failures and […]

Nematic Liquid Crystal Composite Materials for DC and RF Switching

Project by Mohiuddin Munna Liquid Crystals (LC) are widely used in displays, electro-optic modulators, and optical switches. In these types of devices, an electric field is applied which modulates the optical properties of the LC material. It is attractive for its low power consumptions. Opto-electronic devices and switches made from LC materials consume comparatively less power than […]

Novel Test Fixture for Studying Microcontact Reliability and Performance

Project by Protap Mahanta Microelectromechanical systems (MEMS) technology is widely used in applications ranging from sensing to switching technology due to its low cost, low power consumption, and small geometries. Microswitches are an example of a MEMS technology that shows promising performances in direct current (DC) and radio frequency (RF) applications. However, reliability is of great concern for […]
