Welcome to TDK at CES 2019, the world's leading exhibition for consumer electronics, TDK is showcasing its broad and innovative portfolio of sensors, especially for wearable and IoT applications. In addition, products and solutions for automotive and industrial electronics will be shown – in part with live demonstrations.
We’re looking forward to your visit!
Powerful PowerHap™ actuators with haptic feedback
The innovative PowerHap™ piezo actuator with haptic feedback and integrated sensor functionality is available in three compact types – 2.5G, 7G and 15G – which can achieve a very high acceleration of 2.5 g, 7 g and 15 g, respectively, under a load of 100 grams.
These components also offer unrivalled performance in terms of force and response time, and thus offer an unprecedented quality of haptic feedback. The compact and powerful actuators enhance the sensory experience of HMIs significantly by engaging the full range of human tactile sensitivity.
PowerHap is based on multilayer piezo plates with migration-free copper inner electrodes. Thanks to the multilayer technology the actuators can be driven with relatively low operating voltages up to 60 V or 120 V, depending on the type. When activated, the piezo plates only expand minimally in the z axis, but due to the constant volume of the piezo effect contract simultaneously in both the x and y axes. The new component employs cymbals on both sides of the plate as levers to amplify the contraction by a factor of 15 in the z axis.
Compared with conventional electromagnetic solutions such as eccentric rotary motors (ERMs) and linear resonant actuators (LRAs), the PowerHap features high acceleration and force combined with low insertion height and the fastest response time – and all that with extremely low energy consumption per click of 1 mJ, 3 mJ and 8 mJ, respectively, and in a single component with integrated sensor functionality.
Unlike conventional electromagnetic solutions PowerHap actuators can excite the entire stimulation range between 1 Hz and 300 Hz. They thus have no significant frequency or amplitude limitations for customized haptic feedback to key human mechanoreceptors. In this way, the new actuator enables designers to custom develop high-definition haptic feedback profiles that users expect from cutting-edge HMIs. Applications for the PowerHap can be found, for example, in vehicles, smartphones and tablets, household appliances, ATMs and vending machines, game controllers, industrial equipment and medical devices.
Compact CeraPlas™ HF element for cold plasma
CeraPlas™ HF is a compact cold plasma generator element that is based on a PZT (lead zirconate titanate) ceramic and packaged in a plastic housing. CeraPlas HF measures in at just 47.3 mm x 20 mm x 20 mm and its leads are suitable for soldering.
Further notable features are its low weight, low power consumption and low input voltage. CeraPlas HF can be integrated easily and without any special safety measures for protection against high voltage in plasma systems. The new plasma generator is able to ionize different gases – including air – under normal pressure. Because the temperature remains below 50 °C, heat-sensitive materials can be treated with plasma. The combination of compact dimensions and low power consumption therefore makes CeraPlas technology ideal for battery-powered handheld devices.
CeraPlas has a wide variety of applications. It can be used for the surface treatment of plastics, for example, to make them easier to print or write on. Another area of applications is the disinfection of wounds or the sterilization of devices or foods. Moreover, the generation of ozone also enables unpleasant odors to be eliminated.
Precise angular rate measurement with inertial sensors
The Tronics GYPRO3300 MEMS gyro sets a benchmark in angular rate measurement. It is factory-calibrated and temperature-compensated by means of an integral temperature sensor, enabling it to operate with stability and precision over a wide temperature range. It delivers a 24-bit signal via a serial peripheral interface (SPI), and the bias instability and angle deviation exhibit excellent values of just 0.8°/h and 0.15°/√h, respectively. These values far exceed the requirements of the automotive industry.
With its excellent performance in a single-chip solution, the Tronics GYPRO3300 qualifies as best-in-class and also offers compact dimensions of just 19.6 mm x 11.5 mm x 3.7 mm. This MEMS gyro is therefore suitable for extremely demanding applications such as the stabilization of oil drilling platforms, aircraft navigation, attitude and heading reference systems (AHRS), as well as advanced driver assistance systems (ADAS). The compact MEMS inertial sensors are based on the Tronics Magellan process technology that offers a new level of integration, enabling the measurement of as many as 6 axes in a single chip.
