Lab on a Chip - Miniaturisation for Chemistry and Biology | Year: 2014
For the first time we demonstrate a microfluidic platform for the preparation of biosensing hydrogels by in situ polymerization of polyethyleneglycol diacrylate (PEG-DA) in a single step. Capillary pressure barriers enable the precise formation of gel microstructures for fast molecule diffusion. Parallel arrangement of these finger structures allows for macroscopic and standard equipment readout methods. The analyte automatically fills the space in between the gel fingers by the hydrophilic nature of the gel. Introducing the functional structures in the chip fabrication allows for rapid assay customization by making surface treatment, gel curing mask alignment and washing steps obsolete. Simple handling and functionality are illustrated by assays for matrix metalloproteinase, an important factor in chronic wound healing. Assays for total protein concentration and cell counts are presented, demonstrating the possibilities for a wide range of fast and simple diagnostics.

Due to climate related changes, longer dry periods for European farmers and without irrigation the risk of a volatile harvests will rise, that is the reason for a tendency across Europe to irrigate fields. The need for innovative irrigated systems is to minimize water consumption and costs. Also in times of limited water the project will be lucrative. There are more and more increasing cost pressures like costs of water, energy and fertilizer, environmental legislation and requirements, cuts of subsidies, high personal costs etc. The project will help to save a huge amount of money by reducing the mentioned investments. The tendency to automatic systems in the agriculture is rising and in future farmers will do most of their regulating by a computer. The system will support the farmers to realize their work by modern technology. Furthermore the project minimizes the pollution of groundwater by reducing fertilizer to a limit and concerns of eutrophication will be decreased. The aim of the project is to develop a fully automatic irrigation and fertilisation system (with needs based fertilizer spreading) in order to help farmers to monitor and control their water and fertilizer consumption. That basically means we want to combine the irrigation and fertilization in one step. Furthermore, the system will diagnose the need of the plants with the help of sensors and the interpretation of terrestrial meteorological data. The system consists of a combined sensor-detector-dosage system, which includes a monitoring, control and distribution unit which enables the dosing and distribution of the water and the fertilizer.

The first autopilots in airplanes can be traced back to the beginning of the twentieth century. These devices greatly reduced the pilots workload by taking over parts of the navigation. The success of autopilots in reducing navigational complexity and improving safety explains the recent interest to introduce navigational assistance in other transportation means as well. However, implementing robotic navigation correction on a large scale also represents a potential safety risk for its users. For example, some plane crashes have been attributed to the incorrect estimation by pilots of the state of the planes automatic pilot, an effect known as mode confusion.RADHAR therefore proposes a novel framework to design human-aware adaptive autonomy that avoids mode confusion by embedding a thorough understanding of diver behaviour and estimated intention into the decision making. Through lifelong, unsupervised learning, the robot will fuse the inherently uncertain information from environment and driver perception sensors; autonomously estimate the user model and intention and calculate a human-friendly trajectory. Since human characteristics vary over time a continuous interaction between two learning systems will emerge, hence RADHAR: Robotic ADaptation to Humans Adapting to Robots. In order to apply this framework to realistic real-world scenarios, sensor models will be developed to build 3D models of the environment with estimation of dynamic obstacles motion and terrain traversability. To verify driver model assumptions such as focus-of-attention, the drivers posture and facial expression will be estimated with a camera and a haptic interface. The framework will be demonstrated on a wheelchair platform that navigates in an everyday environment with everyday objects. Tests on various levels of autonomy can be performed easily and safely on wheelchairs. Evaluation will happen by a diverse and challenging population of wheelchair users who currently drive unsafely.

The project focuses on the development and prototyping of remotely-controlled, semi-autonomous robotic solutions in domestic environments to support elderly people. In particular, the SRS project will demonstrate an innovative, practical and efficient system called shadow robot for personalised home care.\n\nMost elderly people want to live in the familiar environment of their own residence for as long as possible. However, not many can live with their adult children and therefore, at some stage, often late in life, have to live alone. Studies show that some forms of home care are usually required as they advance in years.\nSRS solutions are designed to enable a robot to act as a shadow of its controller. For example, elderly parents can have a robot as a shadow of their children or carers. In this case, adult children or carers can help them remotely and physically with tasks such as getting up or going to bed, doing the laundry and setting up ICT equipment etc. as if the children or carers were resident in the house. This objective will be realised through the following SRS innovations:\n1) A new intent-based remote control mechanism to enable the robots to be tele-operated over a real-world communication network robustly. 2) An adaptive automation mechanism to enable a highly efficient task execution for remotely controlled service robots. 3) A new robotic self-learning mechanism to enable the robots to learn from their experience. 4) A safety-oriented framework derived through extensive usability and user acceptance studies that enable service robots to be effectively deployed into home care applications.\nThe shadow robot prototypes created with EU support in the SRS project will be tested at the S.Maria Nascente Centre in Milano and the IZA Care Center in San Sebastin. The final solution will be further developed by Hewlett-Packard and other industrial partners of the consortium for a worldwide market with significant potential and volume.

Vibrational Spectroscopy | Year: 2011
In industry, a vast variety of processes can be optimized by means of online measurement of chemical properties of fluids in order to reduce costs of maintenance or increase productivity as well as production quality. Since the absorption measurement in the mid-IR-region is a powerful method to determine the chemical composition of fluids, we propose a fully integrated absorption sensor based on IR-absorption in the evanescent field region of an integrated mono-mode waveguide utilizing thermally generated and detected IR-radiation. For the coupling, two grating couplers are employed, which couple broadband thermal IR-radiation into the waveguide and the attenuated IR-radiation towards a thermal IR-detector, respectively. To achieve a spectroscopic measurement, we utilize the dispersive feature of the grating coupler, which couples the IR-beams out of the waveguide at angles depending on the frequency. We report on the design of the fully integrated infrared absorption sensor, which is capable to determine chemical properties of, e.g., lubrication oil by investigating infrared absorption. Beside the theory related to an optimum design of the mono-mode waveguide, we discuss the applicability of the proposed concept to the monitoring of deterioration of lubrication oil. © 2011 Elsevier B.V.

We present a microchip capillary electrophoresis (CE) device build-up in low temperature co-fired ceramics (LTCC) multilayer technology for the analysis of major inorganic ions in water samples in less than 80 s. Contactless conductivity measurement is employed as a robust alternative to direct-contact conductivity detection schemes. The measurement electrodes are placed in a planar way at the top side of the CE chip and are realized by screen printing. Laser-cutting of channel and double-T injector structures is used to minimize irregularities and wall defects, elevating plate numbers per meter up to values of 110,000. Lowest limit of detection is 6 μM. The cost efficient LTCC module is attractive particularly for portable instruments in environmental applications because of its chemical inertness, hermeticity and easy three-dimensional integration capabilities of fluidic, electrical and mechanical components. © 2010 The Royal Society of Chemistry.

Forensic Science, Medicine, and Pathology | Year: 2014
In this paper we present the second prototype of a robotic system to be used in forensic medicine. The system is capable of performing automated surface documentation using photogrammetry, optical surface scanning and image-guided, post-mortem needle placement for tissue sampling, liquid sampling, or the placement of guide wires. The upgraded system includes workflow optimizations, an automatic tool-change mechanism, a new software module for trajectory planning and a fully automatic computed tomography-data-set registration algorithm. We tested the placement accuracy of the system by using a needle phantom with radiopaque markers as targets. The system is routinely used for surface documentation and resulted in 24 surface documentations over the course of 11 months. We performed accuracy tests for needle placement using a biopsy phantom, and the Virtobot placed introducer needles with an accuracy of 1.4 mm (±0.9 mm). The second prototype of the Virtobot system is an upgrade of the first prototype but mainly focuses on streamlining the workflow and increasing the level of automation and also has an easier user interface. These upgrades make the Virtobot a potentially valuable tool for case documentation in a scalpel-free setting that uses purely imaging techniques and minimally invasive procedures and is the next step toward the future of virtual autopsy. © 2014 Springer Science+Business Media New York.

Within the EC Clean Sky - Smart Fixed Wing Aircraft initiative concepts for actuating morphing wing structures are under development. In order for developing a complete integrated system including the actuation, the structure to be actuated and the closed loop control unit a hybrid deflection and damage monitoring system is required. The aim of the proposed project FOS3D is to develop and validate a fiber optic sensing system based on low-coherence interferometry for simultaneous deflection and damage monitoring. The proposed system uses several distributed and multiplexed fiber optic Michelson interferometers to monitor the strain distribution over the actuated part. In addition the same sensor principle will be used to acquire and locate the acoustic emission signals originated from the onset and growth of defects like impact damages, cracks and delaminations.
