Murata Manufacturing has announced recently the commercialization and mass production of chip inductors featuring industry’s highest inductance value of 270 nH, for the 0603 size. The new inductors are ideal for use in high frequency circuits in such devices as smartphones, mobile phones as well as other type of small mobile devices. Read more
Murata Manufacturing has announced the mass production of monolithic ceramic capacitors on interposer substrates, a first time in the world for a monolithic ceramic that has been used as a countermeasure for squealing, a phenomenon whereby mechanical vibration occurs when a voltage is applied to a ceramic material. Sound is emitted due to the vibration of the printed circuit board. The new installment will provide the interposer substrate with an ability to absorb vibration generated in the capacitor, and greatly suppressing the transmission if vibration to the main board.

Murata Manufacturing has announced the mass production of the DMG Series of highly reliable electric double-layer capacitors which has been designed exclusively for SSD backup applications. The new series offers a low resistance and excellent long-term reliability at high temperatures all with in a super thin package. The low ESR (equivalent series resistance) of 70 milliohm to 130 milliohm enables a high current and high output charging and discharging. Read more
Murata Manufacturing has announced the development of world’s thinnest waterproof piezoelectric speaker featuring an improved sound quality; designed for mobile terminals including smartphones and tablet PCs. Murata has introduced a lineup of ultra-thin piezoelectric (0.9mm thick) in 2011. The new speaker is in compliance with IPX7 grade without use of waterproof sheet like conventional speakers, resulting in reduction in material and installation cost for putting waterproof sheet. In addition to this, the new speaker does not have any magnet, making it free from problems caused by absorbing iron sand, as well as having no electromagnetic noise which may affect magnetic sensors. The new speaker uses a lower primary resonant frequency range. It applications include mobile phones, tablet PCs, mobile internet devices (MID), e-books, portable music players, digital still cameras, digital video cameras, IC recorders, as well as other mobile devices.
Development of Wi-Fi Driver Software for Resource-Constrained CPUs at Low Clock Frequency by Murata Manufacturing
Murata Manufacturing has announced the development of Wi-Fi driver software that can be used with uTRON as well as other type of Real-time OSes (RTOSes). The new driver software makes it possible to provide Wi-Fi capability to resource constrained energy efficient RTOS devices operating at low clock speeds, opening the door for Wi-Fi in OSes other than full-featured alternatives such as Linux and Android. Among some of the features on this newly developed software driver are; introduction of access mode in addition to client mode for operation which results in similar operation to that of the main wireless handset, while providing more robust security than ad hoc connectivity, support for WPA/WPA2 Personal encryption without additional software and support for WPS 2.0 Wi-Fi certified as well as Wi-Fi Direct which enables direct connection between Wi-Fi devices.

Development of Ultra-Slim Low-Resistance Electronic Double –Layer Energy Devices for Maintenance-Free Power Storage Elements
Murata Manufacturing has announced the mass production of ultra-thin low ESR (equivalent series resistance) electric double-layer energy devices. The technology was introduced by Australian component design and manufacturing firm by the name of CAP-XX. The new energy device is capable of flexible charging and discharging from high to low output at a range of temperatures, as well as supporting momentary peak load. In addition to this, the device is capable of leveling battery load as well as driving high-output functions that are normally difficult for batteries alone. Read more
Development of Industry’s First Field-Coupled Wireless Power Transmission Module for Wireless Recharging of Mobile Devices
Murata Manufacturing has announced the development of world’s first field-coupled wireless power transmission module capable of wireless charging of tablet PCs as well as other type of mobile devices. The field-couple system works by positioning electrodes at the power-sending and power-receiving ends and transmitting energy using the electrical fields generated between these electrodes.
The new LXWS series provides wireless power transmission of 10 W through use of the power-sending and power-receiving set. Read more
Development of Next Generation Sensor based Remote Controller Devices using Highly Transparent Organic Piezoelectric Film
Murata Manufacturing has announced the development of a sensor devices based on high-transparent organic piezoelectric film, with high piezoelectric output constant, high transparency (light beam transmittance of 98% or higher) and free from pyroelectric effect. The new film is capable of detecting twisting motion, making it ideal to be used in various applications of human to machine interface. Based on this technology Murata has developed a new remote controller named “Leaf Grip”. Leaf Grip is an innovative remote controller, making your current TV remote control a thing of the past. Leaf Grip close the gap between the current internet connected flat TVs and their remote controllers by controlling the TV using a bending and twisting motion. The remote uses pigments to discharge electrons when it receives light and it is assembled with a photovoltaic cell which converts light into electricity, resulting in battery-less operation.
Twisting the plate on the Leaf Grip will move up/down channels and twisting the plate rapidly will switch the input, while bending the plate will turn the volume up and down and finally banding the plate rapidly or holding one end of the plate and lightly shaking it will turn the power ON or OFF.

Development of Wireless Recharging Pad based on Electric Field Coupling Wireless Power Transmission Technology
Murata Manufacturing and Nissha Printing have jointly developed a prototype of a wireless recharging pad made for wirelessly charging the mobile devices. The newly developed recharging pad has a power receiving circuit for electric field coupling wireless recharging developed by Murata. The other piece of technology that is incorporated into this prototype is integrated into the smartphone, which is a thin and flexible film (electrode) which functions as antenna, developed by Nissha Printing.
