The demand of portable and wearable chemical or biosensors and their expeditious development in the recent years has created a scientific challenge in terms of their continuous powering. As a result, the mechanical energy harvesters such as piezoelectric and triboelectric generator (TEG) have been explored recently either as sensors or harvesters to store charge in small, but long-life, energy storage devices to power the sensors. The use of energy harvesters as sensor is particularly interesting as with such multifunctional operations it is possible to reduce the number devices needed in a system, which also helps overcome the integration complexities. In this regard, TEGs are promising, particularly for energy autonomous chemical and biological sensors, as they can be developed with wide variety of materials and their mechanical energy to electricity conversion can be modulated by various analytes. This review focusses on this interesting dimension of TEGs and presents various self-powered active chemical and biological sensors. A brief discussion about the development of TEG based physical, magnetic and optical sensors is also included. The influence of environmental factors, various figures of merit, and significance of TEG design are explained in context with the active sensing. Finally, the key applications, challenges and future perspective of chemical and biological detection via TEG are discussed with a view to drive further advances in the field of self-powered sensors.
