Embedded usage tracking of helicopter rotating components, combined with active radio frequency identification (RFID) has the potential to reduce maintenance costs, reduce weight, maximize structural life, & enhance safety. Energy harvesting used with advanced, micro-power wireless sensing electronics, enables the realization of truly autonomous sensing and recording. The objective of this SBIR ...

Structural health monitoring (SHM) of large structures such as Navy ships requires an in depth knowledge of operational loads and how these loads may change over time. A network of low cost, wireless strain sensors can provide this information. During Phase I, we will demonstrate a highly synchronized, scalable network of energy harvesting wireless strain sensors. By converting ambient cyclic stra ...

This STTR seeks to develop a high-throughput, low-cost enabling technology for the manufacturing of electronic systems-on-film. It posits a novel concept of introducing percolation networks into semiconducting “inks” to increase by at least an order of magnitude the very low carrier mobilities (

A major barrier to the widespread adoption of wireless sensors for structural health monitoring is the requirement to power the network of wireless nodes. Batteries have a limited lifespan, adding significant size, weight, and costs to the wireless sensor network,and may represent a long term environmental problem. Battery maintenance can be eliminated by harvesting energy from the environment. Fo ...

Structural monitoring of Navy aircraft is of critical importance as the fleet ages. One critical area includes the control surfaces, which are subject to intense, dynamic buffet loading which can lead to structural cracking. The highly transient nature of buffet loading makes it difficult to measure using conventional sensors. We propose to solve this problem by combining a network of time-synchro ...

In Phase 2, Diffraction LTD, in collaboration with Optics 1, proposes to develop a variable magnification clip-on thermal imager (VM-COTI) that will be compatible with a variety of weapon and head mounted optical systems ranging from 1X night vision goggles (NVGs) to 5X ACOG scopes. The VM-COTI will be a flexible design that can be used as a clip-on fusing full field of view thermal imagery with ...

QuantaSpec is a world leader in FTIR spectroscopy applied research. The purpose of this project is to develop and validate methods for the rapid automated detection and identification of Plasmodia in thin film blood smears using FTIR micro spectroscopy. Infrared micro spectroscopy can be used to detect even a single infected red blood cell and is not fooled by artifacts that confound visual micr ...
