カリフォルニア大学アーバイン校の研究者が発明した新しいセルフパワー型の腕時計型ヘルスモニターは、外部電源やバッテリーを必要とせずに、装着者の脈拍を記録し、近くのスマートフォンやタブレットとワイヤレス通信を行うことができます。
学術誌『Nano Energy』に最近発表した論文の中で、バイタルサインをリアルタイムで無線監視するために、柔軟な基板にナノ材料を3Dプリントして構築した発明について述べています。
現在のプロトタイプは、自己発電式の橈骨動脈脈拍モニターとして機能しますが、心拍数、体温、血圧など、健康の他の側面も、センサー回路を変更するだけで測定することができる。

Abstract

Sustainable, self-powered wearable devices that record physiological biosignals are essential in personalized health monitoring but have yet to be achieved. Here a novel, self-powered, MXene-based, 3D-printed, flexible, and integrated wearable system for continuous, real-time physiological biosignals monitoring is proposed, developed, characterized, and validated. The system contains power-efficient triboelectric nanogenerators (TENG), highly sensitive pressure sensors, and multifunctional circuitry. MXene, with distinctive electronegative and conductive characteristics, is the core material and is amenable to 3D-printing. MXene is coupled with a skin-like Styrene-ethylene-butylene-styrene (SEBS) substrate with a positive triboelectric property and high stretchability. This self-powered physiological sensing system exhibited a power output of ~ 816.6 mW m−2, a sensitivity of ~ 6.03 kPa−1, a low detection limit of ~ 9 Pa, and a fast response time of ~ 80 ms, enabling continuous radial artery pulse (RAP) waveform monitoring without external power. Its continuous, on-demand, fully self-powered RAP monitoring and wireless data and power transmission through near-field communication are demonstrated. This is the first report of a wearable system for continuous and real-time physiological biosignals monitoring fully powered by human motion, signaling exciting potential in the field.
