Triboelectric nanogenerators (TENGs) have excellent properties in harvesting tiny environmental energy and self-powered sensor systems with extensive application prospects. Here, we report a high sensitivity self-powered wind speed sensor based on triboelectric nanogenerators (TENGs). The sensor consists of the upper and lower two identical TENGs. The output electrical signal of each TENG can be used to detect wind speed so that we can make sure that the measurement is correct by two TENGs. We study the influence of different geometrical parameters on its sensitivity and then select a set of parameters with a relatively good output electrical signal. The sensitivity of the wind speed sensor with this set of parameters is 1.79 μA/(m/s) under a wind speed range from 15 m/s to 25 m/s. The sensor can light 50 LEDs at the wind speed of 15 m/s. This work not only advances the development of self-powered wind sensor systems but also promotes the application of wind speed sensing.

The use of rapid point-of-care (PoC) diagnostics in conjunction with physiological signal monitoring has seen tremendous progress in their availability and uptake, particularly in low- and middle-income countries (LMICs). However, to truly overcome infrastructural and resource constraints, there is an urgent need for self-powered devices which can enable on-demand and/or continuous monitoring of patients. The past decade has seen the rapid rise of triboelectric nanogenerators (TENGs) as the choice for high-efficiency energy harvesting for developing self-powered systems as well as for use as sensors. This review provides an overview of the current state of the art of such wearable sensors and end-to-end solutions for physiological and biomarker monitoring. We further discuss the current constraints and bottlenecks of these devices and systems and provide an outlook on the development of TENG-enabled PoC/monitoring devices that could eventually meet criteria formulated specifically for use in LMICs.

The present scenario of the world reflects the problem of energy crisis it is facing today. Increasing emissions of harmful gases like various byproducts produced by burning fossil fuels and other flue gases are adding to the worsening environmental conditions. Hence, the need of replenishable and non-conventional sources of energy is more than ever before. TENG or triboelectric nanogenerators show great potential and can be at the frontier of renewable energy technologies in the near future. Among the many applications of TENG as a harvester of abundant environmental energy, the Rotary TENG or the R-TENG is a fascinating newly found type of the same. Rotary TENG has the ability of utilizing the energy present in abundant amount in the environment, like wind energy available in the normal environment of living. Wind speed can also be measured with the help of rotary TENG when used as a self powered sensing elements. This growing field of nanotechnology can be further used in the daily lives of people in coming days.
