Portable energy harvester for self-powered devices

smartphone_pouchWith a focus on using eco-friendly materials such as fabrics worn in daily life (nylon, jeans, cotton, etc.), researchers have developed and demonstrated an innovative product for scavenging biomechanical energy. The team's Smart Mobile Pouch Triboelectric Nanogenerator (SMP-TENG) can generate electricity from lateral sliding and vertical contact and separation with freestanding fabrics; it also can serve as a self-powered emergency flashlight and self-powered pedometer.

New insights into the electrical properties of liquid crystals doped with nanoparticles

LCD_displaysMany of the electronic devices we use in our daily life rely on liquid crystal display (LCD) technologies. LCDs get their name from the special liquid crystal solution that is contained between two thin glass plates inside the display. An electric field applied across the liquid crystal layer changes optical properties of the liquid crystals thus enabling their use in displays. A new paper reports several interesting size effects including monotonous and non-monotonous dependence of the total concentration of mobile ions in liquid crystals on the thickness of the cell and/or on the concentration of nanoparticles.

A guide to the nanotechnology used in the average home

houseThere is an often-asked question: 'When are we finally going to start seeing nanotechnology products on the market?' As a matter of fact, the average home is already filled with products enhanced or reliant upon nanotechnology. In fact, there are several online repositories listing the more than 2,000 commercially available products that incorporate nanotechnology. The application of nanotechnology in some areas, such as batteries, microelectronics and sunscreens is relatively well known. Let's take a virtual tour through a home to see what else we can find.

Nanopore sensor for botulinum toxin detection

botulinum_toxinBotulinum neurotoxins (BoNTs) are the most poisonous substances known to humans, with a median lethal dose (LD50) of 1ng per kg of body weight and are the cause of the life-threatening neuroparalytic illness botulism. Recent assays are very promising for practical use, they require expensive and technically complex equipment. Meeting a need for further development of assays for detection of BoNTs, researchers now have developed a nanopore-based assay for detection of BoNT-B.

Surface state engineering to achieve white LEDs with carbon nanomaterials

carbon_nanoringsWhite-light-emitting diodes have many advantages over forms of lighting - incandescent, fluorescent and halogen - and this solid-state lighting technique is bound to make major inroads into the commercial and household markets. Researchers have now designed precursors and chemical processes to synthesize intercrossed carbon nanomaterials with relatively pure hydroxy surface states for the first time, which enable them to overcome the aggregation-induced quenching (AIQ) effect, and to emit stable yellow-orange luminescence in both colloidal and solid states.

New process allows fully additive roll-to-roll printing of flexible electrochromic devices

electrochromic_deviceElectrochromic devices are some of the most attractive candidates for paper-like displays, so called electronic paper, which will be the next generation display. Researchers have now demonstrated solid state flexible polymer based electrochromic devices are fabricated continuously by stacking layers in one direction. This novel bottom-up approach with no need for a lamination step enables fully printed and 2D patterned organic electrochromics.

Origami batteries for deformable electronics (w/video)

foldable_batteryIn order to fabricate entirely flexible electronic devices, the components that power them - such as batteries - not only need to be fully flexible as well but they have to be compatible with commercially available manufacturing technologies. This would require achieving a high degree of deformability without using elastomeric materials. Researchers have now demonstrated the fabrication of a highly deformable lithium-ion battery using standard electrodes and commercially standard packaging technologies.

Experimental graphene earphones outperform most commercial headsets

earphonesResearchers have exploited the extraordinary electrical and mechanical properties of graphene to create a very efficient electrical/sound transducer. This experimental graphene loudspeaker, without any optimized acoustic design, is simple to make and already performs comparably to or better than similar sized commercial counterparts, and with much lower power consumption. Most speakers available today reproduce sound via a mechanical diaphragm, which is displaced oscillatorily during operation. A wide-band audio speaker typically requires significant damping to broaden the response. Even without optimization, the graphene speaker is able to produce frequency response across the whole audible region, comparable or superior to performance of conventional-design commercial counterparts.
