This proposal describes a Phase II effort that will result in the development of multiple uniquely identifiable, wirelessly interrogable, passive humidity sensors, and a wireless interrogation system to obtain and interpret the sensor responses. The interrogation system used will be a slightly modified version of the system designed by ASR&D for use in the wireless SAW concrete maturity monitoring system currently being developed by ASR&D under funding from the Maryland Technology Development Corporation (TEDCO) and under the NASA Phase II STTR contract NNK07EA38C. ASR&D thinks that this interrogation system, which incorporates coded sensor time diversity with self-synchronization, has significant advantages over the OFC-sensor-based systems previously developed by the ASR&D and the University of Central Florida in terms of increased range and the larger number of sensors that can simultaneously operate without sensor to sensor interference. The proposed Phase II effort has technical objectives that aim (i) to further the development and implementation of the passive wireless SAW humidity sensor technology for which preliminary technical feasibility was demonstrated in Phase I, (ii) to modify existing breadboard wireless interrogator electronics to operate with these sensors, and (iii) to produce prototype sensor devices capable of operation with the modified breadboard wireless interrogator system to produce a multiple sensor system usable for field demonstration of the technology. Wireless system demonstrations will be conducted using laboratory samples of the composites used in wind turbines or other NASA relevant applications. At the completion of the Phase II effort, the sensors and system will be at TRL 4-5.","startYear":2009,"startMonth":9,"endYear":2011,"endMonth":11,"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":[{"transitionId":2236,"projectId":10314,"transitionDate":"2011-11-01","path":"Closed Out","infoText":"Closed out","infoTextExtra":"","dateText":"November 2011"}],"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.
