Mouser Supplies TDK's Ultra-Thin PiezoHapt Actuators
Published2018.02.06 13:07Suitable for temperature and shape changes due to its unimorph structure
Mouser Electronics supplies the ultra-thin PiezoHapt, which expands TDK's portfolio of haptic devices, including actuators. With a thickness of 0.35 mm and a response time of 4 ms, it is thinner and more energy-efficient than conventional eccentric and linear resonant motors.
TDK's PiezoHapt actuator, supplied by Mouser, is designed with a unimorphic structure and consists of multilayer piezo elements attached to one side of the diaphragm. Thanks to the unimorphic structure, it can adapt to changes in temperature and shape and operates at low voltages. It is driven by voltages as low as 24V and exhibits various vibration patterns depending on the amplitude and frequency of the applied voltage. With a frequency of 200Hz and a peak voltage of 24V, the PiezoHapt typically provides a displacement of 65µm (no-load).
It is also an energy-saving haptic solution requiring a diaphragm measuring 80 × 60 mm. It is suitable for applications where haptic feedback technology is applied, such as smartphones, wearables, tablet PCs, displays, touchpads, and industrial control.

The Problem with AI is Not Performance, but Trust
CEO Kang Min-seung emphasized at Snowflake's World Tour Seoul that generative AI has entered a phase where "trust" rather than accuracy becomes the key competitive advantage. As AI is applied to various tasks including consultation, risk management, and operational automation, incorrect data, erroneous responses, and bias are creating actual business risks. He pointed out that enterprises must build a trust layer above AI. To achieve this, accurate data management, semantic structuring, governance, and prompt security are essential. He explained that AI is not merely an automation tool but a technology that reorganizes the entire organization's workflows and decision-making systems. Snowflake provides a platform that supports this trust-based AI operation, emphasizing that enterprises should build "trustworthy AI" rather than "intelligent AI."

The Decisive Factor for AI Agents in Finance: "Trustworthy Data Infrastructure"
The key to spreading AI agents in the financial sector is establishing a trustworthy data system. KB Kookmin Bank is operating over 100 AI agents by 2025 and is promoting expansion to 300. AI is automating repetitive tasks across various areas such as consultation, risk management, wealth management, and relationship management. However, if data quality, governance, and semantic structuring are insufficient, errors and risks increase. KB is building an AI-Ready organization through a multi-model strategy of GPT, Gemini, and Claude, as well as a Snowflake-based data system. The bank emphasized that AI has entered a phase where it restructures not just simple automation but the entire work process and decision-making system.
