随着人工智能（AI）技术快速发展，数据中心数量激增，其对水资源的需求也日益攀升——主要用于 冷却系统与电力供应。据经合组织最新估算，到2027年，全球AI产业耗水量将达到66亿立方米。 世界经济论坛网站在11月20日的报告中指出，实施循环水管理策略可将数据中心的用水量降低75%，这 对保护社区淡水资源至关重要。这些方案包括采用先进的液冷与闭环冷却等技术，实现水资源优化利 用。 数据中心成水资源消耗大户 从日常社交娱乐到复杂AI运算，数据中心始终是数字世界的幕后支撑。然而其运行也伴随着高昂的环 境代价，不仅消耗大量材料与能源，更离不开珍贵的水资源。海量数据运转产生巨大热量，必须借助冷 却设备维持正常运行。 闭环冷却系统则通过密闭循环的冷却介质（如水或专用液体）实现高效散热，广泛应用于工业制造、通 信保障与数据中心等领域。 最具创新性的当属"直达芯片冷却"，通过冷却液或冷板直接接触芯片表面散热，有效避免过热与水资源 浪费。此项技术特别适合缺水地区，可实现20%—90%的节水效益，并降低18%的用电需求。 目前，微软已部署闭环液冷系统；开利公司正投资芯片直冷技术；艺康集团推出的3D TRASAR技术， 能实时监测冷 ...

在实验中，研究团队尝试利用声波"抓取"人体血栓或培养皿中的微小细胞，但传统IDT产生的平面声波 只能推动目标在平面内移动，难以实现空间操控。为此，需要构建能在微尺度上完成复杂运动和精细操 作的"声学手指"，以实现微小目标的精准操控。 研究团队还开发了多种新型片上器件方案，可在不同尺度和功率下运行，并生成不同能量分布的声波。 通过相位编码调控，这些器件能以前所未有的方式对声波进行倾斜、弯曲和耦合。最终，这一整套机制 被集成在单一电子芯片上，形成一体化声波操控平台。实验结果显示，该平台产生的声波能量束在传播 距离和能量集中度方面均优于传统IDT。 美国弗吉尼亚理工大学研究团队在片上声波操控领域取得新进展。他们研制出一种新型可编程声波芯 片，可在电子芯片上对流体和颗粒等微小目标进行灵活精准操控。该技术拓展了医学和工程领域的应用 前景，有望应用于非侵入性手术或体外血液成分分离。相关研究成果发表于最新一期《自然·通讯》杂 志。 该技术的核心优势在于"适应性"。团队能精确控制声波的能量传播方式，使其适用于不同需求，如声波 路径引导、流体和颗粒操控。这项成果不仅开创了可编程片上声波操控的新方法，也为未来在微纳制 造、半导体 ...
