Phase 2 SBIR

Agency: Navy
Topic: N102-181
Budget: 09/30/11 - 03/30/13

Etrema is developing an acoustic projector that provides broad bandwidth, high source level, directional output, high duty cycle, and high reliability in a compact package. Specific objectives of the Phase II effort are: demonstrate performance of a prototype projector, optimize the full-scale projector design, and demonstrate performance of the...

Phase 2 STTR

Institution: Ames Laboratory

Agency: Navy
Topic: N10A-T020
Budget: 09/20/11 - 03/20/13

Development of an energy harvesting system utilizing the magnetostrictive material, Galfenol, will be completed in this effort. The energy harvesting system will consist of Galfenol plates or sheets, magnetic circuit components, coupling structure, power conditioning electronics, sensor, and wireless transmitter. Lab testing and relevant environ...

Phase 1 SBIR

Agency: Navy
Topic: N111-066
Budget: 05/09/11 - 03/09/12

Etrema proposes to develop a free-flooded Galfenol split-ring transducer that will provide 50-75 Hz of bandwidth on a 200 Hz carrier wave capable of operating at depths up to 1000 m with a source level greater than 190 dB re 1uPa @ 1m. While there are no specifications on size, the desire expressed by the technical point of contact is for a sour...

Phase 1 SBIR

Agency: Navy
Topic: N102-181
Budget: 10/18/10 - 08/17/11

Etrema proposes to develop a modified acoustic projector design that provides broad bandwidth, high source level, directional output, high duty cycle, and high reliability in a compact package. The design will target the same acoustic source levels as the baseline Vector Projector with higher duty cycle, lower frequency bandwidth, and a smaller ...

Phase 1 STTR

Institution: Ames Laboratory

Agency: Navy
Topic: N10A-T020
Budget: 06/28/10 - 09/02/11

Energy harvesting devices utilizing magnetostrictive materials are a logical choice for harvesting the high impedance (high force, low displacement) vibrations found aboard Navy ships. Force-based devices, enabled by magnetostrictive materials, can harvest energy over an extremely large bandwidth, approximately ±35 and ±70 Hz currently, making t...

Phase 2 STTR

Institution: Pennsylvania State University

Agency: Navy
Topic: N07-T035
Budget: 02/11/09 - 08/11/10

In the Phase I effort a Galfenol-based slotted cylinder projector (SCP) device was conceived utilizing an existing PZT SCP design and analytical modeling to determine the geometry requirements necessary to achieve the performance specs: 210 dB source level, 750 Hz resonance frequency, 200 Hz bandwidth. The final form factor was a Galfenol SCP wi...

Phase 2 STTR

Institution: Pennsylvania State University

Agency: Navy
Topic: N07-T035
Budget: 10/13/08 - 04/13/10

Etrema Products, Inc. and Applied Research Laboratory at The Pennsylvania State University demonstrated during Phase I that by utilizing the delta-E effect in magnetostrictive materials, the resonant frequency of a split ring transducer can be shifted by over 200 Hz for a low frequency transducer. A variable reluctance driver helps achieve so...

Phase 2 SBIR

Agency: Navy
Topic: N07-075
Budget: 09/22/08 - 07/30/10

The Phase I effort successfully developed an integrated magnetostrictive transducer/amplifier module concept to meet these performance goals: broad bandwidth (7-30 kHz), compact size (approximately ½ wavelength at the center frequency), at least 30 Watts output power, and high efficiency. Conceptual designs of the transducer, amplifier, and th...

Phase 1 STTR

Institution: Pennsylvania State University

Agency: Navy
Topic: N07-T035
Budget: 07/27/07 - 05/27/08

Current ASW missions require low frequency off-board sound sources that can operate monostatically or bistatically. Since these sources may or may not be recoverable, and may require a substantial number to cover the designated operating areas, the low frequency source transducers also need to be low cost. The team of Etrema Products and Appli...

Phase 1 STTR

Institution: Pennsylvania State University

Agency: Navy
Topic: N07-T035
Budget: 07/01/07 - 04/30/08

The size of conventional split ring transducers is much smaller than a wavelength at operating frequency leading to a high Q resonance and limited operating bandwidth. The proposed work will investigate two different modifications to the split ring structure that allow its resonance frequency to be adjusted under active control so that it is al...
