A tablet shows an electrocardiogram, recorded by a network of soft, wireless, wearable sensors.
センサーは互いに通信し、体温、酸素濃度、呼吸、筋肉の緊張、身体活動、心臓の電気的活動など、身体のさまざまな生理機能を継続的にモニターします。
そして、この複合的な活動をアルゴリズムで解析し、異常な心臓のリズムを自律的に検出し、いつ、どの速度で心臓を動かすかを決定します。これらの情報はすべてスマートフォンやタブレット端末に転送され、医師は患者を遠隔でモニターすることができます。

Abstract
Temporary postoperative cardiac pacing requires devices with percutaneous leads and external wired power and control systems. This hardware introduces risks for infection, limitations on patient mobility, and requirements for surgical extraction procedures. Bioresorbable pacemakers mitigate some of these disadvantages, but they demand pairing with external, wired systems and secondary mechanisms for control. We present a transient closed-loop system that combines a time-synchronized, wireless network of skin-integrated devices with an advanced bioresorbable pacemaker to control cardiac rhythms, track cardiopulmonary status, provide multihaptic feedback, and enable transient operation with minimal patient burden. The result provides a range of autonomous, rate-adaptive cardiac pacing capabilities, as demonstrated in rat, canine, and human heart studies. This work establishes an engineering framework for closed-loop temporary electrotherapy using wirelessly linked, body-integrated bioelectronic devices.
