UBITag: A Ubiquitous Optical Wireless Tag for Identifying Objects in the Physical Space

Autor: Ramin Mirjalili, Babak A. Parviz

Publikováno v: IEEE Internet of Things Journal. 2:259-264

In this paper, an infrastructure that enables the association of a unique identification (ID) number to objects in the physical world is proposed. The system consists of a small tag that can be attached to any object. The tag is powered optically and

HARPSS-fabricated nano-gap comb-drive for efficient linear actuation of high frequency BAW resonators

Autor: Farrokh Ayazi, Anosh Daruwalla, Haoran Wen, Ramin Mirjalili

Publikováno v: 2016 IEEE 29th International Conference on Micro Electro Mechanical Systems (MEMS).

This paper presents the design, fabrication and characterization of self-aligned nano-gap comb-drive actuators for high frequency bulk acoustic wave (BAW) resonators. The comb-drive is implemented to actuate a high-Q 1 MHz annulus BAW resonator with

Substrate-decoupled silicon disk resonators having degenerate gyroscopic modes with Q in excess of 1-million

Autor: Haoran Wen, Farrokh Ayazi, Ramin Mirjalili, D. E. Serrano

Publikováno v: 2015 Transducers - 2015 18th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS).

This paper details a center-supported solid disk resonator in single-crystalline-silicon (SCS) that uses a novel substrate decoupling feature to achieve ultra-low dissipation gyroscopic modes with small frequency split. The secondary bulk acoustic wa
