The timing of the assessment of the injuries following a road-traffic accident involving motorcyclists is absolutely crucial, particularly in the events with head trauma. Standard apparatus for monitoring cardiac activity is usually attached to the limbs or the torso, while the brain function is routinely measured with a separate unit connected to the head-mounted sensors. In stark contrast to these, we propose an integrated system which incorporates the two functionalities inside an ordinary motorcycle helmet. Multiple fabric electrodes were mounted inside the helmet at positions featuring good contact with the skin at different sections of the head. The experimental results demonstrate that the R-peaks (and therefore the heart rate) can be reliably extracted from potentials measured with electrodes on the mastoids and the lower jaw, while the electrodes on the forehead enable the observation of neural signals. We conclude that various vital sings and brain activity can be readily recorded from the inside of a helmet in a comfortable and inconspicuous way, requiring only a negligible setup effort.
在涉及摩托车手的道路交通事故后，对损伤进行评估的时机至关重要，尤其是在发生头部创伤的情况下。用于监测心脏活动的标准设备通常连接到四肢或躯干，而脑功能则通常通过连接到头戴式传感器的单独装置进行测量。与此形成鲜明对比的是，我们提出了一种集成系统，该系统将这两种功能整合在一个普通的摩托车头盔内。多个织物电极安装在头盔内部，位于头部不同部位与皮肤接触良好的位置。实验结果表明，可以从乳突和下颌上的电极测量的电位中可靠地提取R波（进而得出心率），而前额上的电极则能够观察神经信号。我们得出结论，仅需极少的设置工作，就能以舒适且不引人注意的方式从头盔内部轻松记录各种生命体征和大脑活动。
