Quick-destructing battery could power 'transient' devices

Quick-destructing battery could power 'transient' devices
Reza Montazami, an Iowa State University assistant professor of mechanical engineering and an associate of the U.S. Department of Energy's Ames Laboratory, has been working on transient technology for years. The latest development from his lab is a self-destructing, lithium-ion battery capable of delivering 2.5 V and dissolving or dissipating in 30 minutes when dropped in water. The battery can power a desktop calculator for about 15 minutes.

Li-ion batteries made of solid materials improve safety

Li-ion batteries made of solid materials improve safety
  Researchers at ETH Zurich have developed a lithium-ion battery made entirely of solid material: it contains neither liquids nor gels. The battery cannot ignite, even at very high temperatures, giving it a safety advantage over conventional batteries. In addition, they allow new forms of battery design.

200mA LDO regulator suits portable & flexible electronics

200mA LDO regulator suits portable & flexible electronics
Supplied in a minuscule 0.47x0.47x0.2mm CSP, a 200mA LDO regulator has been introduced by STMicroelectronics for wearable and portable devices and flexible electronics such as multifunction connected smart cards. The LDBL20’s bumpless STSTAMP package breaks through the minimum I/O-area and height limitation imposed by the diameter of traditional flip-chip solder bumps, enabling unprecedentedly small footprints and low mounted heights.

Converter modules provide solutions for wayside communication

Converter modules provide solutions for wayside communication
The C600 series of DC/DC and AC/DC converter modules has been introduced by Schaefer. The highly-reliable, compact and ultra-rugged 3U design uses industrial-grade components and provides a high-density, space saving solutions for wayside signal and communication installations globally. These units are ideal for redundant systems with two units per 19” sub-rack.
