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.

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

IMPACTS •The WIMS ERC has:– Graduated over 150 doctoral students; offered short courses enrolling over
3500 pre-college students, with 60% selecting engineering careers. – Created 11 startups, with an impact on the State estimated at over $400M.– Led a worldwide revolution in microsystems and its core technology areas. – Demonstrated smart stents, biopsy needles, and intraocular pressure
sensors to improve cardiovascular care, cancer diagnosis, and the treatment of glaucoma.
– Demonstrated low-cost widely-deployable radiation detectors for ensuring the safety and integrity of containerized shipping worldwide.
– Sparked worldwide efforts to develop neuro-electronic interfaces for neuroscience and neural prostheses.
– Realized the first thin-film cochlear electrode arrays, with the prospect of providing improved hearing to millions.
– Developed smart air-quality monitors to help address global warming.– Demonstrated hand-held breath analyzers for biomarkers of tuberculosis
and lung cancer, for use in developed and undeveloped areas of the world.

Technology has passed a tipping point. By combining micropower circuits, sensors, wireless interfaces, power sources, packaging, and nanostructures,
WIMS has unleashed a flood of advances for health care, the environment, the national infrastructure,
and other areas that will change the way we live and improve the quality of life.
The WIMS Institute will continue to drive core research in microsystems and their use in addressing critical
national needs.
