BPN858: Zero Insertion Force MEMS Socket for Microrobotics Assembly

Hani Gomez
2020

To help resolve the control and power challenges present in developing microrobots, the research focus of this project is the design and development of a zero insertion force (ZIF) MEMS socket. The ultimate goal is to achieve an electrical connection between a 65nm single-chip mote, a solar cell chip, and a multi-legged silicon-on-insulator (SOI) microrobot. As proof-of-concept, the most recent socket prototype has demonstrated a successful connection to a MEMS robotic leg chiplet, which is orthogonal to the socket. Both chiplets were fabricated using a two-mask SOI process. The...

Originally from Cochabamba, Bolivia, Hani obtained her BS in Electrical Engineering at the University of South Carolina, Columbia. She is currently pursuing her PhD at UC Berkeley with a focus on MEMS. With Kristofer Pister as her advisor, she is working on developing MEMS/CMOS interfaces for the ultimate goal of creating microrobots.

Design, Fabrication, and Assembly of Multi-chip Walking Silicon Microrobots

Hani Gomez
2020

Microrobots can someday be used as a tool to further expand investigative capabilities– for example, archeologists could use them to research buried cities such as the one in Tiwanaku, Bolivia, or emergency response workers could send robots ahead in search-and- rescue operations. The anatomy of a microrobot can be broken down into its body, brain and power. Typically, each subsystem is fabricated using a different process, creating the need for multi-chip assembly. Microrobots in the literature are often assembled post-process using methods such as wire bonding, silver epoxy, and flip-...

Crystal-Free Wireless Communication with Relaxation Oscillators and its Applications

David Burnett
2019

For the last decade, the size of complete 2.4GHz wireless modules containing everything but power have stagnated at ~1cm x 1cm. This is despite continued advances in semiconductor processes due to components needed by the core communication IC. Breaking this size barrier (which also sets a power and cost barrier) by eliminating all off-chip components is the goal of the Single-Chip Mote project, of which this dissertation is a part. The major components to be eliminated are antenna, battery, and crystal oscillator. Without these components, a complete wireless module could be the size of...
