Joseph Greenspun, Ph.D. 2018

Electrical Engineering
Advisor: Prof. Pister
Research Interests: Human–computer Interaction (HCI), Microelectromechanical systems (MEMS), Wearable Sensors.

BIOGRAPHY
Joseph Greenspun started his MS/PhD program in Electrical Engineering at UC Berkeley Fall 2012 with a concentration in MEMS under Kris Pister. Research efforts have focused on creating a MEMS device capable of fracturing micromachined barriers and membranes. He completed his B.S. in Electrical Engineering and Biomedical Engineering at Boston University, focusing in biomedical optics, in May of 2012.

Self-Destructing Silicon [BPN744]
Funded under the DARPA Vanishing Programmable Resources (VaPR) program, this project explores the fundamental issues associated with making wireless sensor nodes disappear after achieving an objective. The MEMS Hammer is a micromachined device capable of storing mechanical energy and delivering that energy to a target. It has been used to fracture other microfabricated structures made of silicon and silicon dioxide. The MEMS Hammer is capable of storing a wide range of energies with the upper limit exceeding 10uJ. These devices have been characterized to determine the tradeoffs among energy stored, total stroke, and layout area. The MEMS Hammer is being developed for a variety of applications ranging from creating a self- destructing mote to extending the effective lifetime of air-sensitive and moisture-sensitive sensors.
