Transient Electronics Dissolve When Triggered

An Iowa State research team led by Reza Montazami is developing "transient materials" and "transient electronics" that can quickly and completely melt away when a trigger is activated. The development could mean that one day you might be able to send out a signal to destroy a lost credit card.To demonstrate that potential, Montazami played a video showing a blue light-emitting diode mounted on a clear polymer composite base with the electrical leads embedded inside. After a drop of water, the base and wiring began to melt away. As the technology develops, Montazami sees more and more potential for the commercial application of transient materials. A medical device, once its job is done, could harmlessly melt away inside a person’s body. A military device could collect and send its data and then disappear, leaving no trace of an intelligence mission. An environmental sensor could collect climate information, then wash away in the rain. SourceAlso: Read other Electronics & Computers tech briefs.

Wireless Device Senses Chemical Vapors

A research team at the Georgia Tech Research Institute (GTRI) has developed a small electronic sensing device that can alert users wirelessly to the presence of chemical vapors in the atmosphere. The technology, which could be manufactured using familiar aerosol-jet printing techniques, is aimed at myriad applications in military, commercial, environmental, and healthcare areas.The current design integrates nanotechnology and radio-frequency identification (RFID) capabilities into a small working prototype. An array of sensors uses carbon nanotubes and other nanomaterials to detect specific chemicals, while an RFID integrated circuit informs users about the presence and concentrations of those vapors at a safe distance wirelessly.Because it is based on programmable digital technology, the RFID component can provide greater security, reliability and range – and much smaller size – than earlier sensor designs based on non-programmable analog technology. The present GTRI prototype is 10 centimeters square, but further designs are expected to squeeze a multiple-sensor array and an RFID chip into a one-millimeter-square device printable on paper or on flexible, durable substrates such as liquid crystal polymer.SourceAlso: Learn about Extended-Range Passive RFID and Sensor Tags.

Dual-Channel Electromechanical Shutter Driver (ESD)

This device controls the electromechanical shutter in a digital or photographic camera. This electronic device is designed to provide optimal control of an electromagnetically actuated shutter used on a digital or photographic camera. The SD36B1 Electromechanical Shutter Driver is designed to provide the drive pulses for opening and closing an electromagnetically actuated shutter. Electromechanical shutters are used when the exposure period for an electronic camera needs to be controlled outside of the range of electronic shuttering capabilities offered by the camera itself.

Sub-Nanosecond, Compact, Low-Power Time-Interval Measurement

This innovation is a sub-nanosecond time-interval measurement that is compact and inexpensive, implemented in a field-programmable gate array (FPGA). Currently, high-speed count ers or semi-custom or custom ASICs (application specific integrated circuits) are used for time-interval measurements. They are not nearly as powerful for automatic delay control for the environment (manufacturing, temperature, voltage, aging, and radiation).

Improvised Diagnostic Strategy for High-Side Switch Power Stage

This technique enables detection of when a power stage fault occurs, and the type of fault. Robert Bosch Engineering & Business Solutions Ltd., Bangalore, India A vehicle electronic control unit consists of various high-side power stages for driving different loads. Common faults that these power stages experience are Short Circuit to Battery (SCB), Short Circuit to Ground (SCG), and Open Load (OL). These faults can occur during either on-state or off-state of the power stage output. It is essential to diagnose a fault such as SCB during switch off-state, SCG during switch on-state, and OL during both on- and off-state of the switch in order to avoid system malfunction or power stage damage.

Connectors Outperform Hardwiring for Manufacturers and Their Customers

Many thousands of equipment manufacturers have switched from point-to-point (hard) wiring to connector-based cable assemblies in factory and process automation and control systems. Adopting progressive connectivity solutions has improved their unit costs and productivity. It allows them to turn around orders and complete installations much faster. With margins under increasing pressure, many OEMs have come to regard these benefits as a must-have. For many of their customers, the principal argument for connector-based wiring over hardwiring – a lower total cost of ownership over the service life of the machine – is equally compelling.

Powering Wearable Technology and the Internet of Everything

How are the billions of new wearable technology devices and Internet of Everything sensors going to be powered? We do not want to have billions of toxic Primary batteries in our landfills. These new intelligent devices will need to harvest surrounding ambient energy for life-of-product powering. This White Paper describes how new system architectures, energy harvesting technologies and safe rechargeable solid state batteries can be used to create high-efficiency energy harvesting-based systems.
