Presently, Metis Design Corporation (MDC) has demonstrated the patented technique of point-of-measurement datalogging. During the proposed research, MDC will further exploit this SHM architecture to satisfy NASA mission specifications. This work focuses on a Boeing Proprietary technology that allows cable-free transfer of electrical signals. To date, this technology has been demonstrated to successfully power and transfer data from analog sensor arrays. During Phase I, MDC will work with Boeing to demonstrate this technology for a digital sensor bus. The first task will aim to modify the existing sensor hardware to be physically compatible with such a bus. The second task will investigate attachment mechanisms that will provide the necessary electrical connections while not sacrificing strength or structural coupling for wave propagation. The third task will seek to design an impedance matching circuit for the sensor-bus to support multiple sensors for both power and data on the same CAN-style bus. The final task will piece each of these components together to demonstrate damage detection and localization on a composite plate supplied by Boeing.","startYear":2009,"startMonth":1,"endYear":2009,"endMonth":7,"statusDescription":"Completed","programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"SBIR/STTR","active":true,"description":"
The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
