Self‐Powered Intelligent Voice Navigation Tactile Pavement Based on High‐Output Hybrid Nanogenerator

Abstract

Improving the safety and usability of the blind movement is of great significance. The blind navigation system has always been the focus of attention. However, achieving an unconscious interaction and long‐term operation with high navigation accuracy is an urgent challenge. In this study, a distributed self‐powered intelligent voice navigation tactile pavement (SVP) based on a hybrid nanogenerator for blind navigation is reported. More than 4‐s effective output time is achieved under a single instantaneous pressure to the hybrid nanogenerator. The system is integrated with an inertial storage hybrid nanogenerator (ISNG), RF transmitter module, and voice broadcast module. It has the advantages of outstanding navigation accuracy, fatigue resistance (16 000 cycles), temperature stability (−50 to 50 °C), no required operation, and easy fabrication. The SVP may solve the difficulties of GPS navigation delay and lack of map information and realize the accurate identification and feedback of key locations, providing an effective and unconscious interaction navigation strategy for the blind. Integrating the hybrid nanogenerator under the road can provide an energy supply for the construction of the Internet of Things and smart city in the future.

“…Moreover, a distributed self‐powered intelligent voice navigation tactile pavement (SVP) [ 223 ] based on TENG and an electromagnetic generator (EMG) for blind navigation was proposed to enhance the safety of blind movement (Figure 6h ). Composed of an inertial storage hybrid nanogenerator (ISNG), an RF transmitter module, and a voice broadcast module, the SVP can respond to external force incentives within four seconds.…”

A press-rotary triboelectric-electromagnetic hybrid energy harvesting device for indoor IoT node power supply and smart home control

“…[30][31][32][33] According to previous studies on hybrid energy harvesting devices, the energy generated by the environment and human motion can be efficiently harvested by integrating EMGs and TENGs. [34][35][36][37] However, most hybrid energy harvesting devices can only power electronics and cannot effectively utilize the characteristics of TENGs that can be used as a sensor, resulting in a single application scenario and lack of diversity. Therefore, it is important to develop a new energy harvesting device that can simultaneously power electronics and smart sensing to promote the diversication of energy harvesting application scenarios.…”
