Japan's Kyocera Corporation has combined a piezoelectric actuator with a special resin film to produce a proprietary, piezo film speaker that is considerably thinner and lighter than conventional electromagnetic speakers, while boasting similar audio levels. The Smart Sonic Sound already provides the audio for LG's 55-inch curved-screen OLED TV and the company hopes it will give designers of future TVs, computers and tablets more scope to place speakers on the front face of products, enabling an overall size reduction and expanding design options.  Read More

Though there's much work to be done before miniature robots move exactly like insects, Harvard Microrobotics Lab is making strides with its latest prototypes. It recently demonstrated the Harvard Ambulatory MicroRobot (HAMR), a 4.4 cm quadruped that scurries around at up to 8.4 body lengths per second.  Read More

Initial prototypes of the 'blood pressure watch' with the strap made from piezo-resistive ...

Blood pressure is one of the main vital signs, measuring the pressure of the blood upon the walls of blood vessels as it is pumped around the body by the heart. High blood pressure, or hypertension, places increased stress on the heart and can be an indicator of other potentially fatal health problems, such as stroke, heart attack, and heart failure. Most people will have had their blood pressure tested using a sphygmomanometer on a visit to the doctor, but a new wristband device is set to provide a more convenient and continuous way to keep a watch for signs of trouble.  Read More

SolePower and its ankle strap battery

Two years ago, University of Wisconsin–Madison engineering researchers Tom Krupenkin and J. Ashley Taylor developed a device designed to harness the power of walking to charge an internal battery. Now, a new product called SolePower is looking to do the same thing, and its designers are turning to Kickstarter to bring it to the masses. The difference between this and other devices is that it comes in the form of a removable insole, so it can be used in different kinds of shoes.  Read More

Despite being the most common renewable energy technologies, solar panels and wind turbines still have their shortcomings. Particularly when it comes to the urban environment. Lack of space and concerns about noise are just two problems with integrating them into city settings in an unobtrusive way. That's why Belatchew Arkitekter wants to try a different approach with its Strawscraper concept, which proposes transforming the Söder Torn building in Stockholm into an urban wind farm by covering it in piezoelectric fibers.  Read More

Almost since the beginning of their existence, robots have taken inspiration from one of nature's wonders: insects. Technological limitations typically prevent these robots from matching the small size of their many-legged muses, resulting in gargantuan examples like Festo's BionicOpter dragonfly. In stark contrast is Harvard's RoboBee, which is the first in the world to demonstrate controlled flight by an insect-sized robot.  Read More

For years now, scientists across the globe have strived to find a method that gives robots an accurate sense of touch, and with good reason. A robot with an improved ability to feel would be better equipped to identify objects, judge its movements with greater care, and perform more tasks overall. In the latest step towards that goal, researchers at Georgia Tech have crafted a new type of touch-reactive material that's sensitive enough to read fingerprints and could provide robots with a sense of touch that resembles our own.  Read More

A team of researchers at MIT’s David H. Koch Institute for Integrative Cancer Research has developed a new polymer film that generates power from water vapor. Consisting of two polymer films, the material makes remarkably acrobatic somersaults in the presence of even tiny traces of evaporated water, opening the way for new types of artificial muscles for controlling robotic limbs or powering micro and nanoscopic devices.  Read More

The compact radiation source developed by Kovaleski's team at the University of Missouri (...

While we’ve seen developments that could see T-ray spectrometers featuring in a future handheld tricorder-like device, good ol’ X-rays could also get a guernsey thanks to an engineering team from the University of Missouri. The team has invented an accelerator about the size of a stick of gum that can create X-rays and other forms of radiation, opening up the possibility of cheap and portable X-ray scanners.  Read More

GE's dual piezo cooling jet consists of a piezoelectric material (the blue bit) attached t...

Despite their shortcomings, fans do a good job of cooling things down inside PC chassis. Unfortunately, their bulky shape and drain on battery life doesn’t make them a viable option for thinner form factors, such as tablets and smartphones, limiting the processing grunt that can be crammed inside such devices. Inspired by lungs and by adapting technology that improves airflow through jet engines, researchers at GE have created a super-thin cooling device they say will enable thinner, quieter and more powerful tablets and laptops.  Read More
