Just in - the results of our annual Trend Watch Sensors Survey of design engineers, who specify a wide range of sensor technologies in their applications, from basic proximity and photoelectric sensors to more advanced vision systems and energy-harvesting sensor networks. In general, respondents see sensors as growing in importance, with 56 percent saying they expect to see the use of sensors in their designs increase in the next three years. Half of the survey respondents design products for the industrial market. The balance of respondents works in industries as diverse as automotive and aerospace to packaging and healthcare. A full two thirds noted that in particular vision sensors and systems and wireless sensors will become increasingly more important in their design work. Some 15 percent of respondents noted that more traditional proximity, linear displacement and photoelectric sensors also will play a more prominent role in their design work. Hands down, the hottest trend noted in the survey results is wireless sensor networks, with 60 percent of the respondents saying that they see this technology heating up in the next 12-18 months, thanks to greater reliability and easy-to-use, plug-and-play connections. There is also the potential with wireless for significant savings when it comes to installation costs. When selecting a sensor, respondents said that reliability, accuracy and durability/ruggedness are the top three charactertistics, while product support and availability are critical when selecting a particular supplier. On design engineers' sensor wish list is more comprehensive data sheets and technical documentation, especially with regard to new products, as well as the availability of cost-effective sensors that meet the rigors of their applications. "We're looking for the right functionality with good pricing," one respondent noted.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
A group of researchers at the Seoul National University have discovered a way to take material from cigarette butts and turn it into a carbon-based material that’s ideal for storing energy and creating a powerful supercapacitor.
