Official statements A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board Operations Manual shall not be considered or inferred to be the official position

13、 of IEEE or any of its committees and shall not be considered to be, or be relied upon as, a formal position of IEEE. At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall make it clear that his or her views should be considered the per

14、sonal views of that individual rather than the formal position of IEEE. Comments on standards Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membership affiliation with IEEE. However, IEEE does not provide consulting information or advice perta

15、ining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is important that any responses to comments and questions a

16、lso receive the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to comments or questions except in those cases where the matter has previously been addressed. For the same

17、reason, IEEE does not respond to interpretation requests. Any person who would like to participate in revisions to an IEEE standard is welcome to join the relevant IEEE working group.

When a document is more than ten years old and has not undergone a revision process, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to

26、 determine that they have the latest edition of any IEEE standard.

Micro

40、electromechanical systems (MEMS) have become a key enabling technology for many of todays high-technology products, including automotive sensors, smart phones, and the new consumer market of wearable fitness devices. MEMS are also supporting new breakthroughs in areas such as green energy and portab

41、le medical diagnostic and treatment technologies. These factors make them a keystone for advanced manufacturing, jobs, and technology innovation. The MEMS Industry Group (MIG) and its member MEMS companies, large and small, have recognized MEMS testing as a growing industrial issue and a pre-competi

42、tive place in the value chain where cooperation would benefit all competitors and customers. MIG has documented that the lack of testing standards attributes to increasing costs of MEMS device manufacturing. Today, the cost to test MEMS devices is from a third to as much as two thirds of the total m

43、anufacturing costs. Often, the most complex and promising devices have the highest testing costs. The industry group sees an urgent need to standardize MEMS testing whose impact is only increasing as a direct result of advances in MEMS innovation. IEEE Std 2700 addresses the issue of non-uniformity

44、in MEMS sensor data sheets, by defining the sensor performance parameters that are typically used in MEMS sensor technologies. Potential customers use data sheets to select the devices that they will design into their systems. Potential customers use data sheets to compare the performance of devices

45、 from multiple manufacturers. Data sheets contain specifications of the device performance, the package design, operating temperature, input and output signals, etc. Even though the data sheets may not reflect the type of testing that goes into qualification or production test, they should not confl

46、ict with those measurements. This standard is expected to be the first in many that will follow. The performance parameters defined in this standard will each need standard testing protocols to ensure that device performance data measured by any party (buyer or seller) is in agreement and within a d
