Wireless Sensors Push Smart Machines Into Green Revolution

STMicroelectronics, ARaymond and Micropelt to Demonstrate Thermal-Energy Harvesting Solutions at Hannover Fair - Hall 8, D26

Geneva, Switzerland, Grenoble, France, and Freiburg, Germany , March 17, 2011 -

STMicroelectronics (NYSE: STM), ARaymond and Micropelt today announced that they are jointly presenting thermal-energy harvesting-based solutions to power ‘smart sensors’ and ‘smart microsystems’ at the Hannover Fair under the common theme of ‘Green Solutions.’ The three companies are partnering to exhibit the entire value chain of self-sustaining wireless systems in a joint booth (Hall 8, D26).

Wireless sensor and actuator systems are strong future contributors to energy and resource efficiency; the improvement of asset health and uptime; and more efficient condition-based maintenance and operating safety of machines and production equipment. Ubiquitous wireless systems are indispensable to achieving a huge green impact; however, they are a viable option only if local battery maintenance can be circumvented.

Micropelt has developed chip-sized thermogenerators (TEGs) which turn local heat fluxes into electrical energy for ultra-low-power systems. Due to the highest power density in a few square millimeters of footprint, Micropelt’s chip-sized thermogenerators have attracted many customers worldwide. STMicroelectronics, one of the world’s biggest chip makers, and ARaymond, a worldwide supplier to the automotive and solar industries, are presenting solutions they have co-developed with Micropelt.

STMicroelectronics Reveals Innovations for Safer System Operation

Voltage detectors enable enhanced safe recovery in extra applications

Geneva, March 16, 2011 - STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications and a leader in monitoring and protection ICs, has perfected a new generation of innovative voltage detectors with extra features that enhance system safety and reliability for a wide variety of applications.

The STM1831 voltage detector will be used in equipment such as autonomous systems and safety-related devices, enabling the electronics to recover safely if a voltage drop occurs in the power supply. Unlike other voltage monitors, the device has independent connections for the sense input and its own supply voltage. This allows the voltage detector to operate reliably even if the monitored voltage falls to 0V.
