Future flexible and wearable devices will be connected to the Internet of Things (IoT) to improve their performance and communication with users and other sensors. To supply these devices, the mechanical energy of the surrounding environment can be converted into electrical energy-using energy harvesters based on piezoelectric and triboelectric effects. Thus, these systems could substitute conventional lithium-ion batteries. The energy harvesters can be designed using different piezoelectric and triboelectric materials. For this, analytical and numerical models must be developed to predict the optimal performance of energy harvesters, considering their better materials and structural configurations.
For this Special Issue, we welcome submissions of review articles, as well as original research papers related with the design, modeling, fabrication, and characterization of piezoelectric and triboelectric energy harvesters for potential applications in flexible and wearable devices.
