TDK株式会社（东京证券交易所代码：6762）宣布,其InvenSense SmartSonic™ ICU-30201超声波飞行时间 (ToF) 传感器正式进入全面量产阶段。该ICU-30201传感器可提升各类设备的场景感知能力，适用于需要精准检测人体存在、接近和距离测量的应用场景，包括机器人、无人机、报警装置、门锁、摄像设备、智能楼宇系统等。量产已于2025年1月正式启动。
ICU-30201传感器凭借其扩展的最大检测范围，可实现覆盖整个房间的存在感知和远距离障碍物检测，推动了新一代智能家居和智能楼宇设备的创新。作为SmartSonic™传感器系列中的新锐，ICU-30201集成了功能更强大的片上处理器，具有更高的计算能力。TDK提供了包括测距和存在感知在内的多种片上运行算法，不仅能减轻系统主控(MCU)负担、降低功耗，同时支持客户自主编写传感器算法。此外，新型底部开孔封装设计使结构设计集成更为便捷。
TDK集团旗下InvenSense公司工程高级总监Richard Przybyla表示："ICU-30201实现了我们长久以来的愿景——MEMS超声波飞行时间技术是实现室内场景真实存在检测的理想解决方案。凭借其增强的最大检测距离、超低功耗以及可检测人体细微动作的片上处理能力，产品设计师终于获得了一个在性能上超越被动红外(PIR)技术，同时能延长电池续航时间的绝佳选择。"
ICU-30201采用创新型系统级封装，将MEMS PMUT（压电式微机电超声波换能器）与超低功耗SoC（片上系统）集成于微型可回流焊封装中。该飞行时间(ToF)传感器基于超声波脉冲回波测量原理，可在包括强日光照射在内的任何光照条件下，对最远9.5米距离内的目标物进行高精度、高可靠性的距离测量，且测量结果完全不受目标物颜色及光学透明度的影响。
InvenSense的超声波ToF传感器将由无障碍技术公司WeWALK于2025年美国拉斯维加斯消费电子展会 (CES 2025) 期间（1月7日至10日）在TDK展台演示(展位号#15815)。届时，WeWALK还将正式宣布推出带AI导航的Smart Cane 2智能手杖。该手杖采用了包括超声波ToF传感器在内的多款TDK传感器，旨在为视障人士带来便利出行体验。
ICU-30201采用5.17 x 2.68 x 0.9 mm3的超紧凑封装，现已在全球多家授权代理商处开始销售。如需了解更多信息或申请样品，请访问 https://invensense.tdk.com/smartsonic 或发送电子邮件至 inv.sales.us@tdk.com 联系InvenSense销售团队。
