Murata Unveils New EVK-v2 Evaluation Board for Picoleaf Piezoelectric Film Sensor
Film Sensor: With its enhanced flexibility and ease of use, Murata’s EVK-v2 evaluation board offers developers an efficient way
Murata Manufacturing Co., Ltd. has introduced the “EVK-v2” evaluation board, designed to streamline product development with its advanced functionality for the Picoleaf piezoelectric film sensor. This new board integrates a programmable mixed-signal GreenPAK IC from Renesas Electronics Corporation and features an easy-to-use graphical user interface (GUI). The EVK-v2 simplifies function inspections, offering improvements over traditional evaluation boards. Provision will begin in October 2024.
Features of Picoleaf and Limitations of Previous Boards
The Picoleaf sensor is a thin, high-sensitivity piezoelectric film (thickness ≤ 0.2 mm) that detects both pressing force and biological signals such as motion. However, earlier evaluation boards had fixed analog amplification factors, requiring developers to manually modify source code to adjust the on/off detection thresholds. This made sensitivity calibration and function inspection complicated for users.
Enhanced Functionality of the EVK-v2 Evaluation Board
The EVK-v2 addresses these limitations by offering variable signal amplification and digital signal conversion for easy integration with microprocessors. Thanks to the use of the Renesas GreenPAK IC, the board can connect up to 4 sensors simultaneously. Key features of the EVK-v2 include:
- Graphical User Interface (GUI):
- Displays real-time analog signal output.
- Enables dynamic switching of the amplification rate.
- Allows quick adjustment of on/off detection thresholds.
This streamlined design reduces the complexity of evaluating Picoleaf, accelerating product development cycles.
