The demand for a well‐equipped healthcare system is increasing due to the requirement of instant treatment in emergency situations. Particularly, patients are advised to employ fall‐detection sensors and touch‐activated emergency alarms to reduce the mortality rate arising from unexpected falls and emergency conditions. Herein, smart sensors are successfully developed by scavenging the human motions and heat energy with the combination of a triboelectric nanogenerator (TENG) and a thermoelectric generator (TEG). The frictional heat energy produced from the contact and separation of TENG can be utilized as an input source for TEG. Thus, the hybrid tribo‐thermoelectric nanogenerator (HTTNG) generates two electrical outputs with a single primary input. As evidence of this, the flexible HTTNG delivers high output due to the synergistic effect of two generators, that is, through the high output voltage and current in TENG and TEG, respectively. The feasibility of HTTNG as a touch‐activated emergency alarm and a human fall‐detection sensor is successfully demonstrated. Furthermore, the HTTNG can be a promising self‐powered sensing device without any additional power source as well as a power supplier in the Internet of Things era. This hybrid nanogenerator can pave the way for efficient utilization in healthcare systems.

通过将摩擦电和热电结合起来的摩擦热，向先进的智能传感器提高混合纳米发电机的功率性能

由于紧急情况下需要即时治疗，对设备完善的医疗保健系统的需求正在增加。特别是，建议患者使用跌倒检测传感器和触摸式紧急警报器，以降低意外摔倒和紧急情况引起的死亡率。在此，通过组合摩擦电纳米发电机（TENG）和热电发电机（TEG）消除人类的运动和热能，成功开发了智能传感器。由TENG的接触和分离产生的摩擦热能可用作TEG的输入源。因此，混合式摩擦热电纳米发电机（HTTNG）产生两个具有单个主输入的电输出。作为证明，灵活的HTTNG通过两个发电机的协同作用提供高输出，即分别通过TENG和TEG中的高输出电压和电流。成功证明了HTTNG作为触摸式紧急警报和人体跌倒检测传感器的可行性。此外，HTTNG可以成为有前途的自供电传感设备，而无需任何额外的电源，并且可以成为物联网时代的电源供应商。这种混合纳米发电机可以为在医疗保健系统中的有效利用铺平道路。HTTNG可以成为有前途的自供电传感设备，无需任何额外的电源，并且可以成为物联网时代的电源供应商。这种混合纳米发电机可以为在医疗保健系统中的有效利用铺平道路。HTTNG可以成为有前途的自供电传感设备，无需任何额外的电源，并且可以成为物联网时代的电源供应商。这种混合纳米发电机可以为在医疗保健系统中的有效利用铺平道路。
