Key areas where flexible electronics are having a commercial impact are examined by Liam Critchley, who finds smaller companies are carving their own industry niches. The growth of advanced fabrication methods, small-scale nanomaterials and the ability to embed flexible circuitry and components into polymeric hosts have given rise to flexible electronics with advanced functionalities. This has become a popular way ...

Hirose has designed a miniature hybrid flexible printed circuit (FPC) to board connector family called BK22 that can handle signals and power totalling 100W – for USB fast-charging, for example. By “using an FPC to connect the USB to the PCB, the USB can be placed anywhere within the design of the end-product”, according to the company. “BK22 suppresses heat ...

An intelligent patch for cardiac monitoring is amongst research projects built on flexible and stretchable PCBs from Würth Elektronik. There are two cardiac monitors, a mini version with three electrodes for short-term monitoring, and one with six electrodes for longer periods. “A completely new approach to integration was developed in this work,” according to Wurth. “It was based on a stretchable ...

Toyochem  has created a series of flexible conductive and insulating sheet films for the protection of electrical and electronic equipment, including EMC protection. Branded Liotelant “the sheet films exhibit high water-resistance and are highly flexible, with an elongation of 500%”, according to the company. The “films can be hot-press moulded on to the electromagnetic interference source on the PCB, thus ...

GTK is supplying through-hole and sirface-mount flexible jumper strips in a variety of pitches and lengths, with a choice of insulation type. “Flexible jumper strips offer OEMs a versatile method of connecting two PCBs and can tolerate repeated flexing,” said GTK connector specialist Maciej Gluzniewicz. “This is ideal for connecting PCBs in high vibration applications, or where adjoining PCBs are ...

Amphenol RF is aiming at test, measurement and industrial applications with a line of BNC cable assemblies using low-loss Times LMR‐UF cable. LMR cable is designed with improved shielding compared to standard RF coaxial cables and is intended to achieve low attenuation at high frequencies – bandwidth is up to 3GHz. The 50Ω ohm assemblies are available in standard lengths from ...

University of Houston have created an elastic semiconductor with 8.57cm2/Vs charge carrier mobility, and then made transistors, logic and a sensor array from it. Carrier mobility is largely retained when stretched by 50%. The semiconductor concerned is poly(3-hexylthiophene) – ‘P3HT’. This is not the first time the team has made stretchy transistors from this material, but it is the first time that ...

Re-usable flexible medical skin electrodes have been built by combining fabric and chemical engineering at the University of Massachusetts Amherst. Technical performance is similar to commercial wet gel electrodes, while convenience is comparable to dry electrodes – which are easy to use but generally provide inferior signals to wet electrodes. Four of the electrodes have been built into a mask, and ...

University of Toronto researchers have developed a stretchy, transparent and self-powering sensor that records the sensations of human skin. It consists of a layer of hydrogel that can converts mechanical stimuli and humidity into variable resistance and capacitance, as well as self-generating power than can be measured as open-circuit voltage or short-circuit current. Hydrogels are materials with a high water ...

Long-term health monitoring of adults, babies and small children without concern for skin injury or allergic reactions is the aim of a project at Georgia Tech, which has produced a stretchy patch that can broadcast electrocardiogram (ECG), heart rate, respiratory rate and motion activity data. Connections are to gold skin-like electrodes through printed conductors that can stretch with the medical ...
