Establishing design centre for sub 5 Watt DC-DC converters prompts Murata Power Solutions to move UK office Last November Murata Power Solutions’ UK operations have moved to a new facility within Milton Keynes. With an increasing focus on building a centre of design excellence for low power DCDC converters, the company is keen to attract power design engineers to join them. The previous site suited manufacturing and distribution operations that no longer take place in Milton Keynes, so the search was conducted within the local area to locate a facility that better met the requirements of a design and prototype manufacturing operation.

Compact ozonizer module removes germs and eliminates odours Murata introduces the ultracompact MHM500 ozonizer module constructed on a low temperature co-fired ceramic (LTCC) element. Using a discharge electrode and a dielectric electrode within the LTCC board the ozonizer creates a stable supply of ozone, and because the electrodes are fabricated within the LTC element it offers a long life characteristic. Comprising both the LTCC element and a power supply module, the MHM500 can be used to generate ozone in a broad range of consumer, industrial and automotive accessory applications. Bacteria can proliferate in many appliances such as refrigerators and dish washers resulting in mildew, odors and creating potential health risks. Previously, ozone-creating units have been too large and expensive to incorporate into consumer appliances, but now, the

compact MHM500 module makes this possible. The ozone element measures 14.2 x 31.5 x 17 mm, and the power supply module 36 x 50 x 24 mm. The module operates from a +12 VDC input voltage and has a low power consumption of approx 1W. Ozone generation performance is 2.5 mg/h maximum. A remote signal input controls the operation of the unit without the need to turn ON/OFF the input supply. The high voltage output of the power supply module incorporates an over-current and output protection circuit that can isolate the element supply in case of a fault condition.

Applications: - To generate ozone in a broad range of consumer (air-conditioners, refrigerators etc), industrial and automotive accessory applications. Features: - Small size ozone element : 14.2 x 31.5 x 17 mm. - Power supply module : 36 x 50 x 24 mm. - Operates from a +12 VDC input voltage. - Low power consumption of approx 1 W. - Ozone generation performance is 2.5 mg/h maximum. - Generates stable supply of ozone for long life. - Amount of ozone generated can be regulated.

The package measures 4.0 x 2.0 x 40mm in total including the 0.4mm diameter radial leads. The NXRT series is suitable for use in most environments and has an operating temperature range from -40 to +125°C.

MEMS accelerometers target healthcare applications By Alexander Vervuurt, Business Development Manager, Murata Electronics Europe MEMS (Micro Electro Mechanical System) technologies have become widely adopted for navigation and gaming applications through the design of MEMS-based accelerometers and gyroscopes, but another growing use for this miniature electromagnetic sensor approach is in healthcare.

One such popular application is for patient diagnostic equipment for measuring heart performance. The normal way of measuring the functionality of the heart is by measuring the Electrocardiogram (ECG) with a set of electrodes attached to or in contact with the body. You can measure a complex Vectorcardiogram (VCG), the classical ECG with amplitudes and timing of the P-QRS-T waves or just the timing of the R-peak, like in heart rate monitors or sports computers. (See figure 1) Fig 1: P-QRS-T waves in ECG

The Electrocardiogram gives a lot of information about a larger variety of heart defects and diseases as well as about the state of recovery or physical and mental stress of the person measured. However, with ECG you cannot very well measure the mechanical pumping functionality or capacity of the heart. In addition the electrodes could disturb the patient’s normal life by, particularly for leisure activity and specially

for nighttime measurements. Fortunately there are complementary ways to measure the cardiac functionality, like ultra sound monitoring and Ballistocardiology (BCG). The mechanical BCG signal follows the electrical signal with a delay of 30…40 ms. In Ballistocardiology you can measure the mechanical motion of the heart by measuring force or accel-

eration from the chest, but another approach is by taking remote BCG measurements of the blood pumping activity of the heart. With this remote measurement you can avoid attaching electrodes or devices to the body, an advantage for cardiac monitoring in everyday life situations. A single axis measurement in the length direction of the human being is normally adequate as this is the main direction of blood flow.

measure of the heart's beat volume and from the timing one can see the general functionality of the heart as well as the heart rate and its variability, the latter very well describing the recovery state or stress of the person measured. The I and IJ amplitudes in Figure. 2 can be useful in evaluating certain diseases such as aortic valvular disease or coronary artery disease, and even in predicting life expectancy.

BCG offers good perspectives for application in preventive medicine, e.g. in detection of physical or mental stress or in the early detection of coronary heart disease. The amplitudes of the waves (Figure. 2) are a

When measuring the Ballistocardiologic signal with an accelerometer the engineering challenges are the low level of signal acceleration relative to the noise from the sensor and the environment as well as the fre-

quency response and resonances of the mechanical setup, which could be e.g. a weight scale or a bed. BCG from the bed is of particular interest as it enables sleep activity measurement in combination with physical fitness and recovery monitoring, which does not need electrodes and thus does not affect comfort or interfere with the sleep. This type of measurement finds applications in monitoring people with sleep problems related to physical or mental issues as well as in monitoring sportsmen for optimal training effect and avoiding overtraining.

in a hospital bed and separated that from the BCG signal. The residual Ballistocardiologic signal measured from the bed platform can be seen in Figure 3. You can see that there are bed resonances affecting the signal and its decay over time. A reliable measurement of the signal in the 10-3g (cm/s2) range requires a sensor with excellent resolution. One example of a suitable sensor is the SCA121T accelerometer from Murata, this having a noise density of about 14μg/√Hz. By using advanced filtering algorithms the BCG signal can be separated from the bed resonance effects and noise. The resulting estimated heart beats and beat volume can be seen in Figure. 4. The beat volume is expressed in arbitrary units as the transfer function from heart beat to acceleration needs to be calibrated for an absolute value, e.g. in dm3. The beat volume variation in Figure. 4, not being too large, is also a fairly good estimate of the performance of the BCG measurement and the filtering and calculation algorithm. The times between beats in Figure. 4 are of course the Beat-to-Beat times and the Heart Rate Variability (HRV) can be calculated from them as well as the heart rate as a moving average (Figure 5). Murata engineers have also

performed similar BCG measurements on a bathroom scale with the same accelerometer part SCA121T. Heart rate results can be seen in Figure 6. The technology behind a silicon MEMS (Micro Electro Mechanical System) sensor combines the best features and the smallest size, and involves etching (wet and dry), capping (wafer bonding & glass insulation), contacting (solderable and wire bondable electrodes).

Murata. This has a large proof mass which results from using the whole thickness of a silicon wafer, and is capable of withstanding an extremely high shock in the order of 70, 000g. Other key attributes include an over-range capability and the absence of any mechanical hysteresis or plastic deformation resulting from the use of a single crystal silicon structure. Stable capacitive measurement principles achieved with a large parallel plate capacitance coupled with high capacitance dynamics results in a MEMS sensor having an excellent signal to noise ratio. When considering designing a heart monitor based on the ballistocardiology approach, design engineers need to specify a sensor that has a noise density in the order of 14μg/√Hz, this resulting in a measurement resolution better than 1 mm/s2. The ability to avoid detecting unwanted resonances is also critical, such as mechanical vibrations in a building. For this a sensor will exhibit a controlled frequency response, typically achieved by mechanical damping. Finally, advanced signal filtering algorithms should be employed by the sensor package to separate the actual signal from any spurious interference encountered in the operating environment.
