The EagleEye, a 3D sensorsytem for people logistics and tracking “Privacy by Design”

door

Eagle Vision For the public market of People Logistics (healthcare, retail and safety & security) Eagle Vision provides the EagleEye. It is a scalable sensor system used for reliable real-time tracking of people and objects across larger areas.

Based on this tracking data, many applications are available such as direction sensitive counting of people in broad passages, overclimbing and tailgating detection, detecting a fallen person, counting the exact number of persons in a room (for example for access control), measurement of queues and service times, and measuring human behaviour (detection of wandering elderly and
unsafe situations).  The system is based on stereo vision and advanced 3D imaging. The open network interface to external systems makes it possible to process the tracks and other detected events.

Graphene Based Piezoresistive Pressure Sensor

door

Since Andre Geim won the Nobel prize, grapheme is regarded a next new ‘wonder material’. However, where are the applications? Shou-En Zhu of Delft Univerisity of Technology will present a breathtaking one at the Sense of Contact sensorconference: a pressure sensor made from graphene.

With endless hours of work, building and testing his home-built equipment, Zhu successfully produced graphene on cheaper and larger scale than was executed so far. Currently, in order to produce this game-changing material, it requires large and expensive equipment.  The materials engineer was able to design graphene production equipment for 20,000 euros, seven times less than what the current equipment costs.

Zhu claims that he wants to do something new that can benefit society and believes that graphene can change the world and do just that.

Shou-En Zhu will present a pressure sensor based on the piezoresistive effect of graphene. The sensor is a 100 nm thick, 280 μm wide square silicon nitride membrane with graphene meander patterns located on the maximum strain area. The multilayer, polycrystalline graphene was obtained by chemical vapor deposition. Strain in graphene was generated by applying differential pressure across the membrane. Finite element simulation was used to analyze the strain distribution. By performing electromechanical measurements, a gauge factor of ∼1.6 for grapheme was obtained, with a dynamic range from 0 mbar to 700 mbar for the pressure sensor.

Registration For those who did not yet register as a participant in the sensor conference The Sense of Contact 17, it is high time now to do so. It does not make sense to hesitate any longer. For those who are not convinced yet whether it is worth the time and travel to Soesterberg, one look at the brilliant program will be more than enough.

 

Process Industry challenges for new generation sensor technology

door

DSM’s Leon Heemels and FrieslandCampina’s Ids Klompmaker are there at the Sense of Contact 17 sensor conference to challenge all the other participants.
Both representing large companies, they will come forward with their ideas for new developments to apply in future process technology.
A smaller footprint in terms of feedstock and energy consumption, more intensified processes on the molecular level, higher levels of automation, flexibility, quality control and safety requirements, all these targets ask for more accurate, multifunctional, smart sensor technology than is available so far.		 DSMFC1
The conference on April 2nd is the perfect opportunity to discuss the needs and possible roadmaps with them in detail. Being there together with a broad community of sensor technology specialists plus people from academic research groups and STW as the organisation responsible for the funding of promising research proposals, this is the place where the future starts.
