Kurt E. Petersen (born February 13, 1948) is an American inventor and entrepreneur. He is known primarily for his work on microelectromechanical systems. Petersen was elected a member of the United States National Academy of Engineering in 2001.
Petersen received his BS degree cum laude in Electrical Engineering from The University of California at Berkeley in 1970. In 1975, he received a PhD degree in EE from the Massachusetts Institute of Technology. He established a micromachining research group at IBM from 1975 to 1982, during which he wrote the review paper “Silicon as a Mechanical Material,” published in the IEEE Proceedings (May 1982). [1] This paper is a highly referenced work in the field of micromachining and micro-electro-mechanical systems (MEMS); it is considered to have helped establish MEMS as its own branch of technology. [2] As of September 2017, Google Scholar reported 3,795 citations.
Since 1982, Dr. Petersen has co-founded six successful companies in MEMS technology, including Transensory Devices Inc. in 1982 and NovaSensor, a company which develops low-cost micromachined blood pressure sensors using bulk silicon micromachining technology, in 1985. [3] [4] In 1996, he co-founded Cepheid, a company which uses microfluidic technology for rapid PCR detection. [5] Dr. Petersen also co-founded SiTime in 2004 and Profusa in 2008. [6] In 2009, he co-founded Verreon and joined as Chief Technology Officer, helping to coordinate the company’s sale to Qualcomm in 2010. [2]
In 2011, Petersen joined the Band of Angels in Silicon Valley, an angel investment group which mentors and invests in early stage, high-tech, start-up companies. He served as co-chair for the Band of Angel’s hardware subgroup. [2] He joined the Board of Directors for Innovative Micro Technology (IMT) in 2013. [7] [8]
Dr. Petersen has published over 100 papers and has been granted over 35 patents over the course of his career. He is a member of the National Academy of Engineering and is a Fellow of the IEEE. [2]
In 2001, he was elected a member of the United States National Academy of Engineering for "contributions to the research and commercialization of microelectromechanical systems (MEMS)," and he received the Fellowship of the IEEE in recognition of his contributions “for pioneering contributions and successful commercialization of micromechanical systems”. [9] [10] That same year, he was awarded the IEEE Simon Ramo Medal. [11]
In 2002, Red Herring ranked him as a Top Ten Innovator. [12] [13] In 2019, Petersen received the IEEE Medal of Honor. [2]
MEMS is the technology of microscopic devices incorporating both electronic and moving parts. MEMS are made up of components between 1 and 100 micrometers in size, and MEMS devices generally range in size from 20 micrometres to a millimetre, although components arranged in arrays can be more than 1000 mm2. They usually consist of a central unit that processes data and several components that interact with the surroundings.
Micromachines are mechanical objects that are fabricated in the same general manner as integrated circuits. They are generally considered to be between 100 nanometres to 100 micrometres in size, though that is debatable. The applications of micromachines include accelerometers that detect when a car has hit an object and trigger an airbag. Complex systems of gears and levers are another application.
Surface micromachining builds microstructures by deposition and etching structural layers over a substrate. This is different from Bulk micromachining, in which a silicon substrate wafer is selectively etched to produce structures.
Microfabrication is the process of fabricating miniature structures of micrometre scales and smaller. Historically, the earliest microfabrication processes were used for integrated circuit fabrication, also known as "semiconductor manufacturing" or "semiconductor device fabrication". In the last two decades microelectromechanical systems (MEMS), microsystems, micromachines and their subfields, microfluidics/lab-on-a-chip, optical MEMS, RF MEMS, PowerMEMS, BioMEMS and their extension into nanoscale have re-used, adapted or extended microfabrication methods. Flat-panel displays and solar cells are also using similar techniques.

Microoptoelectromechanical systems (MOEMS), also known as optical MEMS, are integrations of mechanical, optical, and electrical systems that involve sensing or manipulating optical signals at a very small size. MOEMS includes a wide variety of devices, for example optical switch, optical cross-connect, tunable VCSEL, microbolometers. These devices are usually fabricated using micro-optics and standard micromachining technologies using materials like silicon, silicon dioxide, silicon nitride and gallium arsenide.

He is the son of former Berkeley Dean of Engineering and former UC Chancellor Karl Pister.
Mike A. Horton is an American engineer and founder of a company producing sensor technology and sensor-based systems.
A MEMSmagnetic field sensor is a small-scale microelectromechanical systems (MEMS) device for detecting and measuring magnetic fields (Magnetometer). Many of these operate by detecting effects of the Lorentz force: a change in voltage or resonant frequency may be measured electronically, or a mechanical displacement may be measured optically. Compensation for temperature effects is necessary. Its use as a miniaturized compass may be one such simple example application.

He was editor in chief of the Journal of Micromechanics and Microengineering (JMM), and currently serves on the editorial board of JMM as well as the journal Microsystems and Nanoengineering.
Microelectromechanical system oscillators are devices that generate highly stable reference frequencies to measure time. The core technologies used in MEMS oscillators have been in development since the mid-1960s, but have only been sufficiently advanced for commercial applications since 2006. MEMS oscillators incorporate MEMS resonators, which are microelectromechanical structures that define stable frequencies. MEMS clock generators are MEMS timing devices with multiple outputs for systems that need more than a single reference frequency. MEMS oscillators are a valid alternative to older, more established quartz crystal oscillators, offering better resilience against vibration and mechanical shock, and reliability with respect to temperature variation.

A nanoelectromechanical (NEM) relay is an electrically actuatedswitch that is built on the nanometer scale using semiconductor fabrication techniques. They are designed to operate in replacement of, or in conjunction with, traditional semiconductor logic. While the mechanical nature of NEM relays makes them switch much slower than solid-state relays, they have many advantageous properties, such as zero current leakage and low power consumption, which make them potentially useful in next generation computing.
