Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is crucial to detect proliferation of nuclear material. Critical challenges include: (a) high sensitivity detection of signature emissions from radioactive isotopes, and (b) cost-effectiveness for deployment of sensor networks across large storage facil ...

TDA Research, Inc. (TDA), designed, built, and tested a dense array of 100 very low cost infrasonic sensors. Due to their low cost (1/100x-1/10x the cost of other infrasound sensors), they can be economically deployed in very large numbers; such large arrays can gather more information than a few expensive sensors. They are sensitive from 0.1 Hz - 100 Hz down to 0.08 Pa. We tested the sensors in s ...

Current methods to discern the differentiation state of stem cells are time-consuming, labor-intensive, costly, invasive, and consequently, ill-suited for clinical applications. To overcome these limitations, we propose to develop a microfluidic stem cell analyzer for accurate, non-invasive identification of the cell differentiation state in conjunction with automated cell sorting at high-throughp ...

The company has developed a silk-derived protein (SDP) for use as a novel ophthalmic formulation excipient that will help to treat the ocular injuries and dry eye pathology that affects over 40 million Americans annually and hundreds of millions of people worldwide. The SDP excipient is designed to enhance tear formulation comfort, longevity, and overall ocular health. This proposal builds on the ...

For applications in DoD satellite systems, devices based on novel nanomaterials offer significant advantages over traditional technologies in terms of light-weight and efficiency. Examples of such novel devices include quantum dot (QD) based solar cells, photodetectors, radars and sensors. However, the response of these devices to radiation effects is not well understood, and radiation effects mod ...

Sweat contains biomarkers that give an indication of human cognitive levels. In this SBIR project TDA Research is developing a modular sweat sensor patch that has the capability to not only carry out real-time monitoring of select biomarkers, but also to

Problem: Currently available resuscitation fluids have been shown to induce detrimental effects on trauma outcomes. Objective: The objective of this proposal is to use the data from the successful Phase 1 studies to guide the continued development and te

The Defense Health Agency (DHA) has identified electrotextiles as a potential means of unobtrusively monitoring health and detecting injury events for military personnel. As such, DHA seeks to understand how e-textile constructs might be best leveraged to sense potential injury events such that individualized care may be administered to support both in-combat self-sufficiency and long-term resilie ...

Wearable devices have grown to meet the demand for continuous, noninvasive vital signs monitoring in the military and civilian health care markets.These devices have largely excluded pulse oximetry because non-traditional sites, such as the chest, arm and legs, pose a challenge. We have previously demonstrated the ability to accurately monitor pulse oximetry on the chest, arms and calf.This projec ...

Commercial off the shelf (COTS) sequential samplers that pull contaminated air through thermal desorption (TD) sample tubes have many limitations that reduce their usefulness when they are used to measure volatile organic compounds (VOCs) in air.In this SBIR Project TDA Research is developing an intelligent thermal desorption tube sequential sampler that can be used for VOC sampling in the workspa ...
