Solar Cells Applied Directly to Silicon Chip Can Power Wireless Sensors

Small solar cells attached directly to a silicon chip can potentially serve as an efficient and reliable power source for wireless sensor networks (WSN). This new technology developed by researchers from the Fraunhofer Institute for Microelectronic Circuits and Systems would greatly simplify large-scale WSN applications, for instance in agriculture.

Trillions of Smart Sensors Will Change Life

In February, six students on snowshoes battled as much as 12 feet of snow to penetrate into the heart of the American River basin.  Moving through dense forests and meadows, they mounted 90 iPhone-sized machines, designed to measure everything from soil moisture to temperature and relative humidity, onto 16-foot poles that beam data to researchers like Steven Glaser, a professor at the University of California, Berkeley.

Geosensors to Support Crop Production: Current Applications and User Requirements

Sensor technology, which benefits from high temporal measuring resolution, real-time data transfer and high spatial resolution of sensor data that shows in-field variations, has the potential to provide added value for crop production. The present paper explores how sensors and sensor networks have been utilised in the crop production process and what their added-value and the main bottlenecks are from the perspective of users.
