MEMS sensors fitted to tennis racquet at the Roland-Garros French Open

Babolat has demonstrated a racquet prototype at the Roland-Garros French Open last week with MEMS (micro electromechanical system) sensors technology to measure elements of a player’s technique.
The racquet uses a motion control system developed by French firm Movea. It is expected to be launched as a commercial product next year.
Movea was selected as technology partner by the tennis equipment manufacturer to develop “the racquet of the future”.
“The racquet will be the first instance where sensor integration has ever occurred in commercially available tennis equipment,” said Sam Guilaumé, CEO of Movea.
“This innovation will enhance the player’s experience by providing a new and fun way to interact with the game through new tools that analyse and help improve performance,” said Guilaumé.

The ‘Babolat Play & Connect’ racquet will be the first-ever MEMS technology enabled racquet with the ability to gather and analyse game data and provide information that could only be manually estimated.

“Our goal has been to develop and provide our customers with cutting equipment that will enhance their tennis performance whether they are at the professional or enthusiast level,” said Eric Babolat, Babolat chairman and CEO.

SLEWS: A Sensorbased Landslide Early Warning System

Active Landslide in Southern FranceDue to the progressive development of urban areas and infrastructure, more and more people settle in environments that are or become endangered by mass movements. This situation is being complicated by the fact that the dependency of our society on a functioning infrastructure and number of human or objects in endangered areas increases at the same time. Early warning and alarm systems are an efficient tool to face landslide hazard and reduce the risk landslides, especially where no other mitigation strategies are suitable. Currently existing monitoring systems for early warning are available in terms of monolithic systems. This is a very cost-intensive way considering installation as well as operational and personal expenses. This displays the demand for modern cost-efficient technologies to upgrade existing and to develop new systems.

The main purpose of the SLEWS project is the development of a prototypic real-time landslide monitoring and early warning system for an efficient landslide hazard management. In this context especially the enhancement of data quality to improve recognition and analysis of hazardous situations and reduction of false alarm rates are of special interest. The whole information chain from data gathering, validation and interpretation to data retrieval, visualization and user specific warning is subject of the research project. The project focuses on innovative web technologies using standards according to the Open Geospatial Consortium (OGC) sensor web enablement (OGC SWE) and cost efficient but reliable micro sensors (MEMS) from the automotive industry. The integration of heterogeneous data and information from various providers may be established by an open platform strategy using the web service technology. The Spatial Data Infrastructure (SDI) integrates modern sensor technologies, data gathering, storage and retrieval as well as services for data validation, processing and alarm generation.

MEMS-packed smartphones are world's biggest wireless sensor net

The ever-expanding ecosystem of smartphone apps owes a great deal to MEMS sensors. Indeed, smartphones, with their always-on Internet access and growing complement of sensor technologies, are quickly becoming the planet’s premier wireless sensor network.

“The cell phone is inherently a sensor; even its microphone gives you information on what type of environment you are in, from background or perhaps traffic noise. By using sensor fusion, you can take information from all of these sensors, even the ambient-light sensor, and create apps that have never been thought of before,” noted iSuppli Corp. analyst Jérémie Bouchard.

MEMS sensors in mobile handsets are allowing apps that not only dazzle users but could one day monitor the pulse of the planet. “We are interacting with the world in a more effective manner today because of the MEMS sensors in our mobile handsets; it’s not just for the gee-whiz factor anymore,” said Karen Lightman, managing director of the MEMS Industry Group (MIG). “All over the world, MEMS sensors are improving the quality of life for those using them.”

Trend Watch Sensor Survey

Design engineers assessment of sensor market evolution reveals Wireless Sensor Networks as the hotest sensor technology, with 60 percent of the respondents saying that they see WSN heating up in the next 12-18 months, thanks to greater reliability and easy-to-use, plug-and-play connections. There is also the potential with wireless for significant savings when it comes to installation costs.

The 2010 Trend Watch Sensor Survey results were published by Design News and half of the survey respondents design products for the industrial market. The balance of respondents works in industries as diverse as automotive and aerospace to packaging and healthcare.

When selecting a sensor, respondents said that reliability, accuracy and durability/ruggedness are the top three characteristics, while product support and availability are critical when selecting a particular supplier.

Wireless Sensors That Live Forever

From IEEE Spectrum:

Soon enough, say some engineers, miniature wireless sensors will be located in spots where it would be inconvenient, to say the least, to change their batteries—inside your body, within the steel and concrete of buildings, in the dangerous innards of chemical plants. But today, even the most robust nodes can be counted on to last only a few years. Ideally, engineers need a sensor that can last forever without external power sources or battery changes. According to research presented in December at the International Electron Devices Meeting, in Baltimore, that dream is within reach.

Two research teams tackled the problem of sensor longevity in two very different ways. Both methods rely on piezoelectric power generation, in which a microelectromechanical systems (MEMS) cantilever converts mechanical motions into electrical power. However, the cantilever’s movements are propelled by very different mechanisms—one by a radioisotope and the other by vibrations harvested from the environment. In a big step forward, both methods fully powered autonomous wireless systems.

eKo Environmental System Enables Plant Disease Prediction

From Crossbow’s blog:

Crossbow Technology’s eKo Wireless Crop Monitoring System now enables users of the breakthrough solution to quickly and easily predict disease conditions surrounding their crops to prevent potential outbreaks. Crossbow Technology, Inc., a leading supplier of wireless sensor technology and inertial MEMS sensors for navigation and control, announced today it has integrated plant disease and agricultural models that will let users calculate Powdery Mildew and Downy Mildew at the touch of a button.

The live data from the eKo Nodes provides growers with better insight into their crop’s health so that informed decisions about when and where to spray pesticides can be made preventing unnecessary chemical usage. The ability to monitor multiple points within the field or vineyard provides a granular level of knowledge regarding the various microclimates and zones. This targeted data of the varying crop conditions in a single location will reduce chemical usage and maximize resources so that users maintain healthier, higher quality crops.
