萝莉影视 Manufacturing Co., Ltd. (hereinafter “萝莉影视”) has developed the “EVK-v2” evaluation board (hereinafter “this evaluation board”) for 萝莉影视’s piezoelectric film sensor Picoleaf™. The Evaluation boards includes Renesas Electronics Corporation (hereinafter “Renesas”) programmable mixed-signal GreenPAK™ IC and intuitively controllable GUI*. The Picoleaf can simplify function inspections compared to conventional evaluation boards, contributing to efficient product development. Provision will begin in October 2024.
萝莉影视’s piezoelectric film sensor Picoleaf is a thin sensor with a thickness of 0.2 mm or lower, capable of detecting pressing force with its high sensitivity as well as bio signals and motion. Evaluation boards up to this point had fixed output analog signal amplification factors, requiring source code modifications to adjust the on/off determination threshold. Therefore, customers were required to perform sensitivity adjustments themselves and function inspections were complex.
In response, 萝莉影视 developed this evaluation board that can variably amplify sensor signals from Picoleaf and convert them into output digital signals recognizable by a microprocessor. By adopting the Renesas GreenPAK, this evaluation board can simultaneously connect up to 4 channels worth of sensors. Additionally, the integrated GUI function has enabled the display of output analog signals, dynamic switching of the amplification rate, and adjustment of the threshold for on/off determination output, among other features. This evaluation board simplifies the evaluation of Picoleaf, contributing greatly to efficient product development.
