“…Recently, triboelectric nanogenerators (TENGs), based on the coupling of triboelectricity and electrostatic induction, have been quickly developed for harvesting mechanical energy with various advantages of low cost, high output, simple structure, facile fabrication, flexibility, and light weight . TENGs are able to convert irregular mechanical energy from different ambient sources into electricity and they can serve as self‐powered sensors for various mechanical motions, such as touch/pressure sensors, acoustic sensors, vibration sensors, speed sensors, biomedical sensors, and human motion sensors .…”

An intelligent human-machine interface (HMI) is a crucial medium for exchanging information between people and electronics. As one of the most important HMI devices, touch screen sensors are widely applied in personal electronics in daily life. However, as the most commonly used touch screen sensor, capacitive sensors can only detect limited kinds of gestures such as touching and sliding. Here, a triboelectric touch-free screen sensor (TSS) is reported for recognizing diverse gestures in a noncontact operating mode by utilizing the charges naturally carried on the human body. Compared with conventional capacitive sensors, the TSS is capable of detecting various gestures such as the drop and lift of finger with different speeds, making a fist, opening palm, and flipping palm with different directions. Based on the TSS, an intelligent noncontact screen control system is further developed, which is used to unlock the smartphone interface by the noncontact operating mode. This research for the first time proposes the concept that taking the human body itself to participate in triboelectric self-powered noncontact sensing and provides a touch-free design concept to develop the next generation of screen sensors. It can alter the usual way that people operating their personal electronics.

Hydraulics provide a unique and widely existed mechanical energy source around us, such as in water or oil pipes, and sewers. Here, a non-contact cylindrical rotating triboelectric nanogenerator (TENG) was developed to harvest the mechanical energy from water flows. Operation of the TENG was based on the non-contact free-rotating between a curved Cu foil and a flexible nanostructured fluorinated ethylene propylene (FEP) polymer film. The free-standing distance between two rotating interfaces avoided abrading of electrode materials. The TENG was able to effectively convert mechanical energy of the water flow into electricity. When driven by water flow, the output voltage and current of the TENG reached 1,670 V and 13.4 μA, respectively. Without any energy storage component, the produced electricity could instantaneously power 12 white light emitting diodes (LEDs) bulbs and a digital timer. This non-contact rotating TENG would provide new opportunities for harvesting energy from many types of hydraulics as a self-sustainable power source for sensing, detection, and protection.

“…It is well known that cotton fabric is an abundant source of cellulose and a cellulose-based piezoelectric nanogenerator has already been discussed above. For the first time, Tang et al 32 have reported the triboelectric effect using simple cotton cloth. From their study, it has been observed that this cotton-based triboelectric generator can generate 660 V voltage and 12.5 μA current.…”

Herein, a fully sustainable, flexible, and bio-based piezoelectric-cum-triboelectric energy harvester has been developed using a simple commodity cotton fabric. In the present study, a novel attempt has been made to prepare a piezoelectric and triboelectric energy harvester in a combined manner from the same fabric substrate. The developed mercerized cotton fabric-based energy harvester has shown a significant open-circuit peak-to-peak voltage of ∼47 V and current of ∼1 μA, simply by finger tapping (under a higher amount of pressure). The same device generated an open-circuit peak-to-peak voltage and short-circuit current of 1.77 V and 100 nA, respectively, in response to impact forces (20 N at 7 Hz frequency) applied using a customized force-imparting device. The reason for the enhanced energy of the device made of mercerized fabric has been correlated with structural characteristics of the fabrics. The piezoelectric response of the cotton fabric-based energy harvester has been observed mainly due to the strong intramolecular and intermolecular hydrogen bonds present in the cellulose chains. These strong hydrogen bonds act as strong dipoles inside the cotton fabric structure, for which the resultant dipole moment is very high. On the other hand, triboelectric response of the device is primarily due to the charges developed at the interfaces of a highly electropositive aluminum electrode and highly electronegative polypropylene (PP) of the respective encapsulated devices as per triboelectric series. The developed piezoelectric-cum-triboelectric energy harvester can successfully be utilized as an efficient wearable to power small-scale electronic gadgets.
