[email protected] Abstract In this paper, we fabricated transparent flexible nanogenerators (NGs) by employing flexible polydimethylsiloxane (PDMS) substrate for the growth of ZnO nanowires. The fully packaged NG showed good transparency with a transmittance of 50–60% in the visible range. The output voltage and current was 8 V and 0.6 mA, respectively, corresponding to an output power density of 5.3 mW/cm. The NG also showed excellent robustness and could stably scavenge energy from the motion of a vehicle. Based on this characteristic, we demonstrated its application as a self-powered sensor for monitoring vehicle speed and detecting vehicle weight. & 2012 Elsevier Ltd. All rights reserved.

متن کاملA self-powered piezotronic strain sensor based on single ZnSnO3 microbelts†
We demonstrated a flexible self-powered system that consists of a strain sensor and a nanogenerator. An individual ZnSnO3 microbelt was bonded at its ends to a polyethylene terephthalate (PET) substrate to fabricate a strain sensor and a single-nanobelt nanogenerator. The sensor and nanogenerator were connected in series and packaged by a polydimethylsiloxane (PDMS) layer. The ZnSnO3 belongs to...
متن کاملA nanogenerator for energy harvesting from a rotating tire and its application as a self-powered pressure/speed sensor.
Harvesting unexploited energy in the living environment to power small electronic devices and systems is attracting increasing massive attention. [ 1–7 ] As the size of the devices has shrunk to the nanoor microscale, the power consumption also decreased to a modest level, i.e., the microwatts to milliwatts range. It is entirely possible to drive such a device by directly scavenging energy from...

Heart-rate monitoring plays a critical role in personal healthcare management. A low-cost, noninvasive, and user-friendly heart-rate monitoring system is highly desirable. Here, a self-powered wireless body sensor network (BSN) system is developed for heart-rate monitoring via integration of a downy-structure-based triboelectric nanogenerator (D-TENG), a power management circuit, a heart-rate s...
متن کاملA nanogenerator as a self-powered sensor for measuring the vibration spectrum of a drum membrane.
A nanogenerator (NG) is a device that converts vibration energy into electricity. Here, a flexible, small size and lightweight NG is successfully demonstrated as an active sensor for detecting the vibration spectrum of a drum membrane without the use of an external power source. The output current/voltage signal of the NG is a direct measure of the strain of the local vibrating drum membrane th...
