Scenttronic prototype transmits five odor classes over a network
According to the supplied report, Ohio State University researchers published a laboratory prototype called Scenttronic that digitizes odors with an AI electronic nose and transmits them through a cloud module to wearable receivers. In a blind test involving 16 volunteers, participants distinguished five odor classes: cake, coffee, orange, red wine and beer. The wearable receiver uses a five-channel piezoelectric atomizer to release preconfigured scent sources and must be held close to the wearer’s face. The report says the system remains a laboratory prototype, supports few odors, and has limited accuracy for complex mixtures. It does not provide a numerical accuracy rate for the blind test, and the prototype replays configured scents rather than generating arbitrary odors.
The report describes Scenttronic as a laboratory demonstration that odors can be digitally sampled, transmitted over a network and replayed through wearable devices. Its limited scent library, constrained performance with complex mixtures and reliance on preconfigured sources define the scope of the reported demonstration.
日前美国俄亥俄州立大学团队在《Science Advances》发布研究成果。他们推出一套名为Scentronic的远程气味传输系统，依靠可穿戴接收装置，首次实现气味数字化后通过网络远程复现，让跨距离“传香味”从设想走向实验室验证阶段。
整套系统分为发射端电子鼻、云端传输模块和接收端穿戴设备三部分。
AI电子鼻捕捉空气中气味分子，识别气味特征并转化为数字信号，借助Wi-Fi上传云端转发；接收端有手环、项链两种穿戴形态，内置五通道压电雾化装置，收到信号后释放对应香氛微粒，使用者凑近就能闻到复刻气味。
测试阶段，团队选用蛋糕、咖啡、橙子、红酒、啤酒五种基础气味开展实验，16名志愿者参与盲测，可准确分辨出这五类气味。
这套设备可以实时传输气味数据，也能把气味样本保存在云端随时调取，未来可用于远程陪伴、线上美食直播、元宇宙感官体验等场景。
研究人员同时表示，这项技术目前仍处于原型实验阶段，局限十分明显：可复刻气味种类很少，复杂混合气味还原精度有限；穿戴设备需要贴近面部才能有效闻香，距离商用还有很长距离。
需要指出的是，它并不能直接凭空生成任意气味，本质是先数字化采样、再雾化释放预先配置好的香源，进而补齐视听之外的感官传输短板。
