Task Description: This NASA Phase II SBIR program would develop comfortable garments with multiple integrated sensor functions for the monitoring of astronauts during long duration space missions. During Phase I, NanoSonic demonstrated the feasibility of using its patented Metal RubberTM sheet and fabric materials as both sensor elements and highly flexible electrodes integrated into prototype instrumented garments. Heart rate and EKG data taken using the Metal RubberTM sensors are essentially identical to those obtained using standard biomedical instrumentation. The combined high electrical conductivity, low mechanical modulus, and environmental robustness of the Metal RubberTM materials make them a lightweight, stretchy and comfortable alternative to conventional metal wiring and cabling. During the proposed Phase II program, NanoSonic would work with a large-volume U.S. textile manufacturer, the sensor and electronics design group of a major aerospace company, and a biomedical sensor and devices laboratory of Food and Drug Administration. NanoSonic would improve the Metal RubberTM materials and methods for their integration as sensor and interconnect materials into instrumented garments, design, fabricate and evaluate the performance of sensor jerseys based on the results of Phase I tests, develop data acquisition electronics needed to interface to standard storage and communication modules, and investigate requirements for scaled-up manufacturing.

POTENTIAL NASA COMMERCIAL APPLICATIONS: Commercial applications of NanoSonic's Metal RubberTM-based instrumented sensor garments similar to the ones developed through this NASA program are for emergency first responders (firemen, police, disaster relief personnel), the sports clothing industry, automated home and institutional health care, and the military and homeland security market. NanoSonic's patented Metal RubberTM materials and their unique combination of high electrical conductivity, low mass density, and low modulus will enable the penetration of this broad e-textile products area. Additional uses include as 1) electrical interconnects in truly flexible electronic displays, from large-area billboards to foldable computer screens, 2) large-area deployable photovoltaic fabrics for electrical power generation, 3) low-weight RF shielding and ground planes for cellphones, computers and other electronic instrumentation, 4) low weight, conformal RF phased array antennas for communication, asset tracking and surveillance, 5) air flow and water flow sensors for commercial aircraft and ship systems, and 6) electrical interconnects in next-generation prostheses.

Research Impact/Earth Benefits: Metal RubberTM materials may be used as conformal and comfortable replacements for metal electrodes and wiring used in physiological sensor networks to monitor the status and performance of astronauts during long duration space missions. Due to its high conductivity and low mass density, it also may be used as a flexible, low weight alternative to conventional copper in instrumentation wiring onboard spacecraft. Electrically conductive, mechanically flexible, and ultralightweight Metal RubberTM fabrics may be used as part of large area RF antennas, space-based radar and photovoltaic arrays that are foldable and stowable for launch, then deployable in space. Additional aerospace uses include as ultralow-weight RF/EMI shielding and ground planes for spacecraft and aircraft, as highly flexible conductive fairings and electrical interconnects in next generation morphing air vehicles that change their shape to optimize flight conditions, and as conformal "sensor skins" for the unobtrusive measurement of aircraft skin friction and pressure.
