A -- COMMERCIAL OPPORTUNITY FOR MANUFACTURING OF PIEZOELECTRIC WAFERS POC Linda Fitzgerald, Industry Assistance Office, (804) 864-2461. In order that potential participants may learn of high displacement piezoelectric actuators, sensor materials and devices, an advanced notice is published here. The THUNDER technology is a new NASA Langley Research Center development which has significantly improved the existing state-of-the-art. Thunder actuators provide inordinately large mechanical output displacements - laboratory demonstrations have shown displacements to be as high as 40-50 times the thickness of the device. THUNDER's output amplitude is an order of magnitude greater than existing devices over the frequency range from DC to several kHz, indicating the capacity for a low- frequency device operation. With further development, THUNDER wafers are expected to operate at lower voltages, allowing their use in some applications unsuitable for other piezoelectric materials, such as artificial heart pumps and other biomedical applications. The THUNDER device owes its unprecedented output motion to the special pre-stressed state of its piezoelectric element. THUNDER devices consist of a piezoelectric layer intimately attached to the pre-stressing layer, using a NASA-LaRC polyimide adhesive. The fabrication process for THUNDER devices is easily controlled resulting in highly uniform devices. In addition, THUNDER devices can be specifically tailored to the desired applications. THUNDER devices can be fabricated using any available piezoelectric materials-not just those containing lead, such as PZT-based materials. NASA envisions using THUNDER devices for valve actuation, optical mount stability control, positioners, noise suppression, pumps, flow shaping, and many other applications. This notice announces NASA's interest and desire to enter a joint development and commercialization agreement with private industry to advance the development and testing of this technology, and to transfer NASA's existing proprietary technology and patent rights resulting from joint work under the development agreement(s) by making it available for license to the joint participant(s) in accordance with NASA's Patent Licensing Regulations. Accordingly, a technical briefing will be held on March 5 & 6, 1996, at NASA's Langley Research Center, Hampton, Virginia 23681-0001 to describe the technology, outline the planned Space Act Agreement, and explain the process and criteria under which NASA will select a participant(s). Interested organizations should submit an expression of interest and a statement of qualifications, including: technical experience and competence in the technology, related manufacturing capabilities, experience in commercializing similar products, marketing organization (including resources and capabilities to reach and support targeted markets), and financial status of the firm. This synopsis is for information and planning purposes only and is not to be construed as a commitment by NASA nor will NASA pay for the information solicited. Respondents will not automatically be notified of the results of the evaluation, but those deemed fully qualified will be considered in any resulting requirement. This is not an announcement of an RFP. Expressions of interest should be directed to Rebecca Watkins (412)-648-7005. In responding reference SS247.(This synopsis was previously advertised on December 1, 1995). (0030)
