2 WSN for the Train Industry A new intelligent way has been developed for performing online analysis of rotating train wheel disc. A complete system is able to measure four wheel discs simultaneously. The radio communication has been tested in real operating conditions in the test train without any problems even if the train was running over 300 km/h. 2

3 Torque Measurement from Cardan Axle Rotating cardan axle is probably one of the most challenging scenarios concerning torque measurement. Reliable communication link has been established by using state-ofthe-art technologies. Combined with new strain sensing method breakthrough in mobile condition monitoring has been realized. 3

4 Winder Vibration Management Vibrations in the winding process could cause folding in the paper roll. In-core measurement unit is able to register vibrations in 3D during winding process. Radio communication is reliable despite rotation and paper mass. 4

5 Car Winter Testing Flexible wireless battery operated acceleration measurement system has been used for car winter testing in Lapland. Compact measurement module can be easily installed in few minutes to car body. Online data visualization and storage takes place on portable PC. 5

6 Ski Jumper Analyser Tool for the coach to analyse the ski jumper's performance. Wireless sensor node combines the inertial parameters to the positioning information from the pseudolites or GPS. 6

7 Condition monitoring The bandwidth between the transmitter and receiver of a wireless measuring device might become a bottleneck in a wireless sensor networks for example in structural health monitoring. Additive random sampling as a signal sampling method will decrease the amount of data to be sent wireless. The main advantage of this method in a wireless measurement network is the reduction of the data flow to be processed. 7

10 Time Accurate Wave Propagation Measurement Distributed sensor network that allows phase accurate real time measurement from multiple points New possibilities for monitoring of large structures The measurement range can be extended to several hundred meters by adding more base stations to the synchronized sensor network Extremely accurate synchronization between measurement nodes ~10 ns for base stations and wired sensors (IEEE 1588) ~1 s for wireless sensor nodes (nanonet) 10

11 Mobile phone compatible wireless sensors Existing (Bluetooth) and emerging (NFC - Near Field Communication, Ultra low-power Bluetooth) short range wireless technologies of mobile phones bring along a cost-effective and easy-to-use access to various sensors in our environment. This often makes the user interface and networking parts of the sensors unnecessary and thus reduces the sensor costs, power consumption and physical size dramatically. Mobile phone compatible energy consumption meter (demonstrated by VTT): 1. The Measurement Probe monitors the current in the mains wire of the lamp inductively. 2. The Sensor Front End amplifies and filters the analog signal from the Measurement Probe and converts it to digital format. The Sensor Front End is developed by VTT on Crossbow s MICAz platform. 3. The Smart NFC Interface accumulates the measurement results from the Sensor Front End, converts the results into human readable format, and sends the results to a mobile phone either by Bluetooth or by NFC. Contrary to Bluetooth, NFC enables ultra-low power consumption of the sensor and intuitive touch-based interaction with the sensor by a personal mobile phone. The Smart NFC Interface platform is developed by VTT for rapid demonstration of NFC and Bluetooth enabled devices. 4. The Mobile Phone displays the results to the user. The Mobile Phone incorporates an application software developed by VTT. 11 For example, the power consumption of any electrical appliance could be monitored by a tiny NFC or Bluetooth enabled sensor module according to the figure below

12 Near field communication and Smart NFC Interface Near Field Communication (NFC) is a new standard based short-range wireless technology that is based on earlier radio frequency identification (RFID) technologies and enables easy-to-use touch-based and safe two-way interaction among devices. NFC is backed by a standardisation organisation ( with over 100 members and the first RFID technology that is penetrating into commercial mobile phones Smart NFC Interface is a highly integrated interfacing module prototype developed by VTT for piloting sensors and devices with NFC and/or Bluetooth communication. By embedding or connecting a Smart NFC Interface module to existing or new devices under development, these devices can be made NFC- or Bluetooth-enabled and thus also capable of touch-based interaction with mobile phones and other mobile terminals

14 Smart NFC Interface, blood pressure monitor pilot A commercial blood glucose meter enhanced with NFC communications and back-end support for improved selftreatment of diabetes patients. The idea is to transmit the blood glucose level to a back-end system, which will provide instructions for care in return (instructions for insulin administration). Status: Prototype with VTT Smart NFC Interface and Nokia 6131 NFC phone implemented Preliminary field trials

16 Pioneering micro- and nanotechnology will help diabetes patients: Big ambitions for a tiny implant Source: A technology developed by the Norwegian company Lifecare AS can help millions of diabetics worldwide, and contribute to industrial development in Norway in the process. By employing completely new, groundbreaking micro- and nanotechnology, the small startup company is seeking to revolutionise diabetes treatment - while making the lives of diabetes patients simpler and safer. Diabetics check their blood sugar levels several times each day by pricking a finger and squeezing a drop of blood onto a glucose meter. Their monitoring kit has to accompany them wherever they go. Lifecare is collaborating with eminent international research groups at the Swiss Center for Electronics and Microtechnology, Inc. (CSEM) and the University of Glasgow, which are providing assistance in creating the membrane. Finland's leading technological research institute, VTT Electronics, as well as 3M of the USA and MicroTEC of Germany are also providing expertise
