Nextreme's New eTEG HV56 Thermoelectric Power Generator Cranks Up The Juice

Nextreme Thermal Solutions, the leader in microscale thermal and power management products for the electronics industry, today announced the availability of the new eTEG™ HV56 thermoelectric power generator, the next entry in the high-voltage (HV) series of clean energy generators based on thin-film thermoelectrics, that operates at temperature differentials as low as 10 degrees K. When combined with batteries and energy cells, the HV56 offers an ideal steady-state energy solution for a variety of self-powered applications in the wireless sensor, automotive, aerospace, industrial and medical device markets.

The HV56 is capable of producing 1.5mW of output power and an open circuit voltage of 0.25V at a 10K ΔT in a footprint of only 11mm². At 50K ∆T, the HV56 produces 36.5mW of power and an open circuit voltage of 1.25V. The module is extremely thin: only 0.6mm high, and can be configured electrically in series to produce higher voltage and power outputs.

The use of thermoelectric power generators (TEGs), in which a temperature difference creates an electrical potential, can convert waste heat from thermal sources into electricity for an alternative source of energy. In reality, most heat sources come and go and the actual temperature difference depends on several factors such as the time of day, wind speed and heat output, among other variables. Trickle charging energy storage devices using an HV56 power generator offers an ideal solution to provide steady-state energy from variable heat sources.

"For trickle-charging applications using thermoelectrics, a power convertor is required to meet the minimum charge voltage of the cell, such as 3.3 volts for lithium ion batteries," said Dave Koester, vice president of engineering at Nextreme. "Our new HV56 power generator, in conjunction with the latest advances in voltage up-conversion, enables our customers to get the voltages they need at very low ΔTs."

The high voltage output of the HV56 is enabled by Nextreme’s proprietary micro-scale thermoelectric technology. Certain applications (e.g., generating power off the heat of the human body, or generating power for wireless sensors) require a high density of thermoelectric elements in order to generate power at low temperature differentials. Nextreme’s patented thermal bump fabrication process can achieve thousands of elements per square centimeter.

Nextreme engineers are currently working with customers in a variety of industries and applications. These include clean energy harvesting and storage solutions for wireless sensor networks and remote power management.

The eTEG HV56 is RoHS-compliant and manufactured using eutectic gold-tin (AuSn) solder, which enables assembly temperatures as high as 320°C. The module is available with an 8 to 10 week delivery lead time. Pricing is available upon request.

Nextreme recommends the use of its thermal modeling, design and engineering services to deliver fully-optimized energy harvesting solutions. Nextreme routinely conducts analytical and numerical thermal modeling at all design levels from component to module to subsystem. Advanced analysis of complex systems, components or packages often require more detailed modeling to understand heat flow and thermal gradients.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
