The Economics of Accuracy in Low-cost, High-volume Sensing Applications

Various research firms forecast the market for portable medical devices to be somewhere around the $20 billion-range within the next several years. Part of the increased demand is due to an aging population with more chronic conditions. These smaller portable units requires devices with smaller footprints. By the same token, smaller devices need to provide adequate levels of care to ensure patient safety and comfort. Thus, functionality cannot be sacrificed for space.

Pyramid Micro-Electrofluidic-Spray Propulsion Thruster with Integrated Attitude and Thrust Vector Control

NASA’s Jet Propulsion Laboratory, Pasadena, California

A micro-electrofluidic-spray propulsion (MEP) system was built on a micro scale, in which arrays of hundreds of nano-thrusters are etched on silicon wafers like ICs, only a centimeter on a side. Many dozens of these thruster chips can be arrayed to form a macro-thruster of finite and significant thrust. Approximately 300 centimeter-square, 100-micro-Newton micro-thrusters are arrayed in a square pyramidal structure. The pyramid is of shallow obliquity, with no more than 20° offset from the spacecraft face. This small angular offset is sufficient to provide thrust vector control (TVC) for the thruster.

Linear Motors

Heidenhain (Schaumburg, IL) offers ETEL ILF and ILM series ironless high-speed linear motors for use in the semiconductor and electronics industry. The motors utilize an ironfree coil design for zero-attraction force between the carriage and the magnetic way. The ILF is a smallersized motor for very high dynamic and low-moving mass applications; the ILM is a more powerful version of the ILF, and has an option to be air-cooled to increase continuous force output. The ironless motors come in a variety of lengths and heights with different degrees of force, and share the same profile so that one is interchangeable with the other. The motors can reach speeds of up to 20 m/s and peak force of up to 2,500 N. They are designed for direct drive applications and offer no backlash, fewer parts, and require no maintenance.

Self-Powered Intelligent Keyboard Could Provide Additional Security

By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered, non-mechanical, intelligent keyboard could provide a stronger layer of security for computer users. The self-powered device generates electricity when a user’s fingertips contact the multi-layer plastic materials that make up the device.

Zinc Oxide Materials Power Tiny Energy Harvesting Devices

Many types of smart devices are readily available and convenient to use. The goal now is to make wearable electronics that are flexible, sustainable, and powered by ambient renewable energy. This last goal inspired researchers to explore how the attractive physical features of zinc oxide (ZnO) materials could be used to tap into abundant mechanical energy sources to power micro devices.

They discovered that inserting aluminum nitride insulating layers into ZnO-based energy harvesting devices led to a significant improvement of the devices’ performance. The group’s findings are expected to provide an effective approach for realizing “nanogenerators” for self-powered electronic systems such as portable communication devices, healthcare monitoring devices, environmental monitoring devices, and implantable medical devices.

Glass as Electrode Makes Batteries More Efficient

Today’s batteries provide a reliable power supply for our smartphones, electric cars and laptops, but are unable to keep up with the growing demands placed on them. Researchers have discovered a material that may have the potential to double battery capacity: vanadate-borate glass. The glass is being used as a cathode material, which is made of vanadium oxide (V2O5) and lithium-borate (LiBO2) precursors, and was coated with reduced graphite oxide (RGO) to enhance the electrode properties of the material.

The vanadate-borate glass powder was used for battery cathodes, which were placed in prototypes for coin cell batteries to undergo numerous charge/discharge cycles. In tests, the glass electrodes demonstrated a vast improvement in these batteries’ capacity and energy density.

Mechanically Induced Nucleation Improves Crystalline Quality During Melt Growth of Semiconductors

Significantly lower supercooling results in the ideal growth condition of single crystal nucleation.

Marshall Space Flight Center, Alabama

For certain semiconductors with important applications, the existing bulk crystal growth technique from the melt usually results in poor-quality multi-crystalline ingots that cause the typically low yield of the commercial growth process. The low-quality, multi-grained crystal growth is mainly caused by the large supercool of the melt, which prohibits the ideal growth condition that a small, single-crystal nucleus forms at the very tip and grows into a large single crystal. For instance, semi-insulating cadmium zinc telluride (CdZnTe) crystal is a highly promising material for room-temperature x-ray and gamma ray detectors. However, the major hurdle in using the CdZnTe crystals is its cost. The ability to pack many data acquisition channels (hundreds) with the stopping power for high-energy radiation requires large single crystals of CdZnTe.
