WIRELESS INTEGRATED MICROSYSTEMS (WIMS)

The WIMS ERC was formed recognizing that technology was approaching a tipping point. By

combining six things, a flood of advances could be unleashed to improve health care, the environment,

the national infrastructure, and other areas, changing the way we live and improving the quality of life.

THE WIMS ERC HAS BEGUN THIS REVOLUTION

ERC IMPACTS ON EDUCATION• The WIMS ERC has made extensive contributions to education, graduating

over 150 PhDs to date. Five new microsystems courses have been createdto form the cornerstones of UM M.Eng. and Certificate programs.

• The multi-year Integrated Microsystems Enterprise program at MichiganTech has enrolled >175 students to date, with 79 graduations.

• The ERC has offered 72 K-12 short courses to date, enrolling 3424 students(including (for 7-12) 1055 women and 1319 minorities) and changing manylives. Over 60% of HS graduates have entered college in engineering.

• WIMS is an ideal tool for encouraging more of our young people to pursuecareers in science and engineering, addressing what is increasinglyrecognized as a critical national problem.

WIMS UNDERGRADUATE PROGRAMS

MTU

• Undergraduates are now routinely involved in graduate research, reaching well over 100 students per year and aided by programs such as REU, LSAMP/REU, WUGR, and REU/WUGR

• The Integrated Microsystems Enterprise (IME) program at Michigan Tech is a multi-year undergraduate project experience engaging teachers and delivering data-gathering hardware to seven Upper-Peninsula high-schools. It has involved over 175 students to date.

Activated Microglia/Macrophages

For both ED-1 (microphages) and IgG (blood-brain barrier)

staining, the extent of the reaction zone is greatly

reduced along with the amount of reaction.

For the blood-brain barrier, the reduction is much more

dramatic than for macrophages, reaching a peak

of only 15 within the lattice holes themselves

• Identifies spikes, saving 10-15X in system bandwidth and increasing the number of channels from 25 to 312.

• Operates at 1.2mW from a 3V supply and a 2.56MHz clock with a die size of 2mm x 3mm.
