  1. A Survey on the Guinness Book of Sensors Advanced Topics in Wireless Networks Omar Amarin 4/7/2008

  2. Smallest Sensors Epson, eCAM, Kionix, Samsung • Largest Deployment of Sensors Department of Primary Industries (DPI) • Longest Lifetime Sensors Transducer Technology, Inc. 2

  3. Smallest Sensors 1. Epson (uFR-II) Advanced Model of World's Smallest Flying Microrobot from Epson (August 2004) • Micromechatronics technology • The world's new lightest and most advanced microrobot • The uFR-II is only the latest chapter in an Epson success story that began with Monsieur, a microrobot that was listed in the Guinness Book of Records as the world's smallest microrobot. 3

  4. Problem: Limited Range • Solution: Fully wireless operation paired with independent flight capability. The world's smallest and lightest sensor. • Wireless features - Epson's own sensor (world's smallest and lightest) 4

  5. World's Smallest Gyro-Sensor (December 2004) • The XV-3500CB, Characteristics: • Features of the newly developed XV-3500CB Sensor: • 1. Subminiature SMD • 2. Outstanding stability • 3. Sleep mode 4. Airtight structure 5

  6. 2. eCAM: Ultra Compact, High Data-Rate Wireless Sensor Node with a Miniature Camera • constructed by plugging a VGA video camera to the Eco node. • Eco is an ultra-compact, high-bandwidth wireless sensor node developed by authors. It measures only 13mm(L) × 11mm(W) × 7mm(H) and weights 2 grams. • Great Power Consumption • Other Advantages Authors: Chulsung Park and Pai H. Chou Center for Embedded Computing System, University of California, Irvine. 6

  7. Some Properties: • Ultra-Compact Form Factor: 13x11x7mm, 2grams • 2.4GHz Radio, 128 Channels, 1Mbps • On-Board 3-Axis Accelerometer, Temperature Sensor, • Optical Sensor • Low Power Consumption • 40mAh Li-Polymer Rechargeable Battery, Continuous Listening: about 4 hours • Flex-PCB Expansion Port: Analog/Digital I/O, SPI, UART, I2C, and Interrupts, 7

  8. 3. Kionix, KXPS5, June 30, 2006 • The device, the KXPS5, is just 0.9 millimeters thick, The sensor measures acceleration and is primarily used for free-fall detection in hard drives. • The KXPS5 family of products was specifically engineered to have a very small form factor so that they can be incorporated directly into the hard disk drive. • use specifically in the hard drives of mobile-electronic devices such as cell phones and iPods. 8

  9. How it works • Other Uses: computer and video gaming, global positioning systems, sports diagnostics, and vehicle-stability applications. 9

  10. 4. Samsung, 8.4MP CIS, September 8th, 2005 Sensor Size: 9×6.5 mm Power consumption: 10 mW. More importantly, the sensor’s output is not an analog signal but a digital signal. Micro unit (MCU)” Intelligent function 10

  11. Ideas to Help in the Future • New custom printed circuit boards (PCBs): • Leads to: (Risks) • Extra hardware development effort • Risking introduction of new errors 11

  12. Largest Deployment of Sensors World's Largest Agricultural Wireless Sensor Network Department of Primary Industries (DPI) • Nectarine orchard covered with 47 nodes, 273 sensors. • Sensors include soil moisture, soil and air temperature, canopy temperature, humidity, leaf wetness, trunk diameter, wind speed and direction, solar radiation and GPS co-ordinates. 12

  13. Problems: • 1. Interruptions • 2. Rainfall • Good Ideas: They have started to monitor the sensor network using alerts that are automatically transmitted to a mobile phone by SMS. 13

  14. Longest Lifetime Sensors Transducer Technology, Inc. • High performance • No recharge is required for more than a year. • “Pocket CO” D6F-P MEMS-based D6F-P air flow sensor 14

  15. Problems & Enhancements. Algorithm Up to Five times better lifetime 15
