“…In fact, the output performance of a self‐driven sensor is related to many factors, such as the thickness of the contact materials, the materials, the contact area of the materials, vertical contact forces and contact‐separation frequency, etc. We discuss the effects of contact frequency, contact area, and elastic materials on the performance of the output voltage while controlling other factors as the same.…”

Flexible self‐driven sensors can respond to tiny vibrations such as sound waves, blood pressure, heartbeat, etc., and have attracted great attention for their promising applications in wearable devices, in which the electrical signals are triggered by mechanical strength and the coupling of triboelectric and electrostatic induction. Herein, flexible self‐driven sensors assembled with a chitosan (CS) film and polydimethylsiloxane (PDMS) film selected as positive and negative triboelectric layers, respectively, are presented. Conductive fabrics function as electrodes, and polyurethane (PU) foams function as flexible substrates which have advantages of simple integrated structures, ease of manufacturing, and relatively low costs. Tests confirm that the sensor has outstanding flexibility, excellent response performance, and remarkable stability. It is used for real‐time monitoring of human movements, and is based on textiles, providing wearing comfort and is operated without any external power sources as the output voltage of about 30 V can support it. Owing to these advantages, it is believed that a new and convenient strategy to fabricate a novel sensor based on available materials used for human activity detecting and healthcare monitoring is achieved.

“…For instance, the direct template method has been widely used due to its simplicity as it does not require additional equipment for its preparation. 15,[19][20][21][22][23][25][26][27][28][29] The typical procedure of the direct template method consists to prepare a mixture between the elastomer, the ller dielectric nanoparticles and some kind of particle that will be later dissolved to generate the porous structure, Xia, et al 23 used sugar particles of different sizes and at different concentrations and silver nanoparticles (Ag-Nps) as llers. Aer the elimination of sugar particles, porous structures with embedded Ag-Nps were obtained and used as tribo-materials of TENGs.…”

“…As one of triboelectric materials, polydimethylsiloxane (PDMS) is most commonly used in TENG because of the high electronegativity, easy fabrication, transparency, biocompatibility, flexibility, and low cost. [ 18,19 ] In order to enhance the output performance of TENG, besides selecting materials with larger difference in polarity or changing the substrate morphology, increasing the contact area of materials is also an effective approach. [ 15,20 ] Porous microstructure modified in PDMS is fabricated for decreasing effective thickness and increasing contact area through the large surface area‐to‐volume ratio to improve performance.…”

Triboelectric nanogenerator (TENG), a green energy harvester, can harvest mechanical energy from human motion to electric energy to be applied in wearable electronics and sensor network. Porous materials played an important role in enhancing electric performance of TENG. In this paper, Azobisisobutyronitrile (AIBN) is used as a self‐reactive agent to modify Polydimethylsiloxane (PDMS) to form a self‐assembled porous structure (PDMS‐N10 film) through the difference in temperature between PDMS pre‐curing and AIBN decomposition. The PDMS‐N10‐based TENG exhibits a 2.5‐fold and 2.7‐fold improvement in output voltage and current as compared with PDMS without modification respectively. In addition, 116 light‐emitting diodes could be lighted up and 22 µF capacitor is charged. The TENG is also used as a sensor or trigger device for sensing the movements of elbow, knee, wrist, or finger, which can be applied in wearable devices because of the flexibility and durability as well as low cost.
