Test on Triboelectric Nanogenerators: Principles and Applications

Question 1: The triboelectric sequence of FPPE-2 containing 25% DHPZ exhibited the expected shift compared to FPPE-1 without DHPZ.

A. Yes

B. No

Explanation: FPPE-2 containing 25% DHPZ showed a particular negative shift compared to FPPE-1 without DHPZ, which was different from what was expected, not the expected shift.

Question 2: According to Wang et al. (71), what specific enhancements were achieved in dc TENGs by adjusting the metal/perovskite Schottky junction?

A. An increase in the internal electric field

B. An enhancement in the interfacial electric field

C. An increase in the charge density

D. A reduction in the overall service life

Explanation: The study materials state that Wang et al. (71) enhanced the interfacial electric field and the charge density by adjusting the metal/perovskite Schottky junction. The internal electric field is mentioned as a separate component, and there is no mention of a reduction in service life due to this adjustment.

Question 3: TENG self-powered sensor networks can be utilized for environmental quality monitoring.

A. Yes

B. No

Explanation: Wireless self-powered TENG sensor networks have been rapidly developed for environmental (water, air, and soil) quality monitoring.

Question 4: According to the study materials, which of the following are advantages of TENG self-powered sensors compared to traditional sensors?

A. They require a continuous external power supply, similar to traditional sensors.

B. They offer high efficiency and compelling sensing performance, including high sensitivity and short response time.

C. Their preparation is complex, leading to higher construction costs.

D. They are a reliable strategy to address the significant power consumption challenge of traditional sensors.

Explanation: The study materials state that TENG self-powered sensors have the advantages of being 'additional power supply needless, simple preparation, low limitation, and high efficiency', and they have a 'compelling sensing performance compared with tradition sensors, including high sensitivity and short response time'. It also explicitly mentions that TENG self-powered sensors are 'a reliable strategy to solve the problem of the horrible power consumption of traditional sensors'.

Question 5: The bionic fin-shaped seafloor energy-harvesting device (BFM-TENG) was inspired by a butterfly's curved shell.

A. Yes

B. No

Explanation: The BFM-TENG was inspired by bionic fins with excellent hydrodynamic properties, as stated in the study materials. Other TENG devices, such as the butterfly TENG, were inspired by different bionic elements like a curved shell.
