SWaP-C and Why Your Component Partner Matters

The military is continually pushing to decrease the size, weight, power and cost (SWaP-C) of its electronics, particularly for items carried by the troops. To meet these goals, everyone involved in designing and manufacturing the device needs to work together closely to ensure maximum efficiency of every component. This makes choosing the right partner crucial. Our white paper explores why SWaP-C is so important and includes information on:

Carbon Nanofibers Synthesized on Selective Substrates for Nonvolatile Memory and 3D Electronics Applications

NASA’s Jet Propulsion Laboratory has developed a nano-electro-mechanical resonator (NEMR) based on vertically aligned carbon nanofibers (CNFs) that is suitable for applications requiring high sensitivity, broad tenability, low loss (high Q), low power consumption, and small size. Other nanoscale resonators have been demonstrated using top-down fabrication approaches, but these generally involve complicated and expensive electron beam lithography. JPL’s bottom-up fabrication approach yields robust, vertically oriented CNFs that can be used to form high-Q, high-frequency NEMRs. In addition, the resonant frequency of these NEMRs can be tuned by selecting the length and diameter of the CNFs. This allows for a highly integrated, ultra-low-power, high-data-rate, and wide-bandwidth NEMR-based transceiver architecture.

A Nanotube Film Electrode and Electroactive Device Fabricated with the Nanotube Film Electrode and Methods for Making the Same

Applications include optical devices, electromechanical energy conversion, medical devices, sonar, and transducers.NASA’s Langley Research Center offers an all-organic electroactive device system fabricated with single-wall carbon nanotubes (SWCNT). The enhanced design offers higher electroactive performance in comparison with conventional electroactive device systems fabricated with metal electrodes or other conducting polymers. The new structure allows for significant improvement of the electroactive strain due to relief of the constraint on the electroactive layer. It exhibits superb actuation properties and can withstand high temperatures with improved mechanical integrity and chemical stability. In addition, the electroactive device can be made transparent, allowing for use in optical devices. NASA is seeking development partners and potential licensees.

Superconducting Transition Edge Sensors and Methods for Design and Manufacture Thereof

Superconducting Transition Edge Sensors and Methods for Design and Manufacture ThereofNASA technologists have developed a novel, superconducting transition edge sensor (TES). Such TES devices are thermometers that are widely used for particle detection, e.g. X-rays, infrared photons, atoms, molecules, etc. Energy resolution is chiefly important in superconducting transition edge sensors to function as imaging spectrometers. For optimal energy resolution, it is necessary to control the superconducting transition temperature for the device.

Chalcogenide Nanoionic-Based Radio Frequency Switch

The electrochemical switch is non-volatile, lacks moving parts that can fail, and is easy to fabricate.NASA’s Glenn Research Center has developed nanoionic-based radio frequency (RF) switches for use in devices that rely on low-power RF transmissions, such as automotive systems, RFID technology, and smartphones. These groundbreaking nanoionic switches operate at speeds of semiconductor switches, and are more reliable than microelectromechanical systems (MEMS) switches while retaining the superior RF performance and low power consumption found in MEMS, all without the need for higher electrical voltages. In this new process, metals are photo-dissolved into a chalcogenide glass and packaged with electrodes and a substrate to form a switch. Since the nanoionic-based switch is electrochemical in nature, it has certain advantages over switches that are mechanically based, including nonvolatility, lack of moving parts that can fail, ease and efficiency of activation, and ease of fabrication. This innovative device has the potential to replace MEMS and semiconductors in a wide range of switching systems, including rectifying antennas (rectennas) and other RF antenna arrays.
