- 2015-06-25 Early warning system for dikes passes field test
- Sensors and intelligent systems for analyzing sensor data can detect damage to dikes at an early stage, and thus protect longer dike segments as well. Technology developed by Siemens for this has now passed its field test, which was conducted on a chain of sensors spread out along a length of five kilometers of a dike in Amsterdam. The sensor system permanently records and transmits data on the dike's condition. Experts believe such automated dike monitoring can reduce maintenance costs by ten to maximally 20 percent.

- 2015-06-24 Paper electronics could make health care more accessible
- Flexible electronic sensors based on paper—an inexpensive material—have the potential to some day cut the price of a wide range of medical tools, from helpful robots to diagnostic tests. Scientists have now developed a fast, low-cost way of making these sensors by directly printing conductive ink on paper. They published their advance in the journal ACS Applied Materials & Interfaces.

- Survivors of stroke or other neurological conditions such as spinal cord injuries, traumatic brain injuries and Parkinson's disease often struggle with mobility. To regain their motor functions, these patients are required to undergo physical therapy sessions. A team of researchers from the National University of Singapore's (NUS) Faculty of Engineering has invented a novel robotic walker that helps patients carry out therapy sessions to regain their leg movements and natural gait.

- 2015-06-24 Tech review: Another year, another iPad
- Some years, Apple introduces a new version of a product and the world rejoices. Other years, the updates are more under the hood, but they still sell a ton.
With the iPhone, it has taken to an every-other-year release schedule.
For example, the iPhone 4 was followed a year later by the 4S. The same goes with the iPhone 5 and 5S. - See Details

- University of Twente doctoral candidate Natalia Hoog has developed an online sensor which can be used to check the quality of the water in a water purification plant more accurately and more cheaply. Amongst other things, the sensor can measure the amount of rust, salts, bacteria or alcohol a liquid contains. With this sensor the water purification companies and other companies can save a lot of money, as they can better assess when they have to replace or clean the installations and pipes.

- 2015-06-24 Thin, strong bond for vacuum seal
- An ultra-stable, ultra-thin bonding technology has been adapted by researchers in PML's Semiconductor and Dimensional Metrology Division for use as a super-strong vacuum seal.
Though it is less than 100 nanometers thick, the bond can withstand pressure up to 2 megapascals (almost 300 pounds per square inch), and its drift, or how much it shifts over time, is on the order of less than 3 trillionths of a meter per hour. - See Details

- 2015-06-24 Health checks will be seated by Sharp
- Sharp unveiled a news-making prototype of a sensor earlier this month at Semicon Japan 2014, which took place from Dec 3 to 5. As its title suggests, Sharp's "Blood Vessel Aging Degree Sensor" can measure the degree of aging of your blood vessels. This is important as it enables the detection of trouble ahead—diabetes or arteriosclerosis or other medical problems- at an early stage.
The sensor, after all, can do what conventional blood glucose level sensors cannot—and that is, it can visualize the degree of aging of blood vessels. The sensor quantifies the accumulation of advanced glycation endproducts (AGEs), which are protein saccharified in blood vessels and are known to have a correlation withblood glucose level. - See Details

- 2015-06-24 A control knob for fat? Protein that makes other proteins also regulates fat levels
- Like a smart sensor that adjusts the lighting in each room and a home's overall temperature, a protein that governs the making of other proteins in the cell also appears capable of controlling fat levels in the body.
The finding, which appeared in Cell Reports on Dec. 11, applies to the Maf1 protein in worms.
A version of the protein, which exists in humans, also regulates protein productionin the cell, raising the possibility that it too may control fat storage. A protein with such a function would offer a new target for pharmaceuticals to regulate fat, said Sean Curran, assistant professor at the USC Davis School of Gerontology and the study's corresponding author. - See Details

- 2015-06-23 Detecting extraterrestrial life using mechanical nanosensors
- Looking for life on other planets is not straightforward. It usually relies on chemical detection, which might be limited or even completely irrelevant to alien biology. On the other hand, motion is a trait of all life, and can be used to identify microorganisms without any need of chemical foreknowledge. EPFL scientists have now developed an extremely sensitive yet simple motion detector that can be built easily by adapting already-existent technology.

- 2015-06-23 Fujitsu develops ring-type wearable device capable of text input by fingertip
- Fujitsu Laboratories today announced the development of a compact and lightweight wearable ring-type device that offers handwriting-input functionality and a reader for near-field communications (NFC) tags. Wearable devices have been making inroads into the workplace in recent years, notably with head-mounted displays (HMDs), in line with putting ICT to use so as to not stop what they are doing. But HMDs do not make it easy to select displayed information such as "yes" or "no," to input figures, make notes on workplace conditions, or perform other necessary actions.

- 2015-06-23 Engineers develop graphene-based biosensor that works in three ways at once
- One of nanotechnology's greatest promises is interacting with the biological world the way our own cells do, but current biosensors must be tailor-made to detect the presence of one type of protein, the identity of which must be known in advance.
University of Pennsylvania engineers have now devised a new kind of graphene-based biosensor that works in three ways at once. Because proteins trigger three different types of signals, the sensor can triangulate this information to produce more sensitive and accurate results. - See Details

- 2015-06-19 Researchers equip humans with magnetic sense
- Scientists from Germany and Japan have developed a new magnetic sensor, which is thin, robust and pliable enough to be smoothly adapted to human skin, even to the most flexible part of the human palm. This is feeding the vision to equip humans with magnetic sense.
Magnetoception is a sense which allows bacteria, insects and even vertebrates like birds and sharks to detect magnetic fields for orientation and navigation. Humans are however unable to perceive magnetic fields naturally. Dr. Denys Makarov and his team have developed an electronic skin with a magneto-sensory system that equips the recipient with a "sixth sense" able to perceive the presence of static or dynamic magnetic fields. - See Details
