Outline of Research at the Start

本提案研究では、(a) アンビエントバックスキャッター通信の性能向上とバッテリレスIoTデバイスの開発、(b) 複数のバッテリレスIoTデバイスを協調させたセンシング機構の考案、(c)安定したアンビエントバックスキャッター通信の実現、(d) Wi-Fi電波の乱れを併用した行動認識技術の創出などの研究を行う。そのために、電波伝搬解析ツールや電波暗室などを用いて実環境での性能を解析し、人やモノの移動で生じるWiFi電波の乱れを高精度に検知する仕組みを構築すると共に、センサから得られる低サンプリングレートでのセンシング情報をもとに、人の行動認識を行える仕組みを開発する。

Outline of Final Research Achievements

In recent years, a wireless communication technology called ambient backscatter communication has been developed that can reduce power consumption to about 1/10,000th (tens of Micro Watt) of the conventional level by fluctuating radio waves present in the environment, such as TV and WiFi. In this research, we have developed a mechanism that enables simultaneous sensing using multiple backscatter tags by realizing different frequency shifts for each backscatter tag, and constructed a mechanism that enables sensing without battery supply using small solar cells. In addition, we have created behaviour recognition technology that combines channel state information (CSI), such as Wi-Fi radio wave interference, and other information.

Academic Significance and Societal Importance of the Research Achievements

一般にIoTデバイスでは、センシング、プロセス、通信の3つの処理に電力を消費し、センシングは数十μWレベルで実装出来るものが多いが、WiFiやBLEなどの無線通信は十数ミリWから百ミリW程度の電力を要し、IoTデバイスのインターネット接続のキーとなる技術は超低消費電力の通信方式の普及にある。アンビエントバックスキャッター通信は、TVやWiFiなど環境に存在する無線波にゆらぎを与え、そのゆらぎ成分を取り出す方式で、消費電力を従来の1/10,000程度(数十μW)に低減可能である。本研究では、ゆらぎ成分の効率的な捕捉方式や、複数のセンサーから同時発信される信号波の分離手法などを考案した。
