Multifunctional electronic textiles (e-textiles) incorporating miniaturized electronic devices will pave the way toward a new generation of wearable devices and human-machine interfaces. Unfortunately, the development of e-textiles is subject to critical challenges, such as battery dependence, breathability, satisfactory washability, and compatibility with mass production techniques. This work describes a simple and cost-effective method to transform conventional garments and textiles into waterproof, breathable, and antibacterial e-textiles for self-powered human-machine interfacing. Combining embroidery with the spray-based deposition of fluoroalkylated organosilanes and highly networked nanoflakes, omniphobic triboelectric nanogenerators (R F -TENGs) can be incorporated into any fiber-based textile to power wearable devices using energy harvested from human motion. R F -TENGs are thin, flexible, breathable (air permeability 90.5 mm s −1 ), inexpensive to fabricate (<0.04$ cm −2 ), and capable of producing a high power density (600 µW cm −2 ). E-textiles based on R F -TENGs repel water, stains, and bacterial growth, and show excellent stability under mechanical deformations and remarkable washing durability under standard machine-washing tests. Moreover, e-textiles based on R F -TENGs are compatible with large-scale production processes and exhibit high sensitivity to touch, enabling the cost-effective manufacturing of wearable human-machine interfaces.

“…One of the ways to meet up this demand can be harvesting unanimously available mechanical energy from the environment which is widely known as energy scavenging. Various effects like Piezoelectric, Electrostatic, Electromagnetic, Pyroelectric and triboelectric effects are generally being used for harvesting this type of environment friendly energy [9][10][11][12][13][14]. Particularly, the recently invented Triboelectric Nanogenerators have been in great attention to the experts for powering electronic devices and sensory application through contact triboelectrification and electrostatic induction [15][16][17].…”

“…TENG was first developed by Fan et al in 2012 after the introduction of the concept of nanogenerator in 2006 by Wang et al [18,19]. Since then, TENG with low cost, high power density, light weight, good flexibility and good efficiency has been developed which in turn promoted its application in driving small electronics device and sensors [3,9,16,[20][21][22][23][24]. The power density has been reported as high as 500 Wcm -2 by Zhu et al while a ultra-high energy efficiency of 70.6% has been reported by Tang et al [25,26].…”

In recent times, Triboelectric Nanogenerators (TENG) have attained the focus of the scientific community due to its potential as a medium to harvest mechanical energy from the ambient environment. Human motion has been attributed as a source of mechanical energy to drive electronic devices and sensors through TENG. Based on the principles of single electrode TENG, we have developed a Triboelectricity based Stepping and Tapping Energy Case (TESTEC) which magnifies the prospect to power touch electronic devices by utilizing finger tapping and stepping motion. This novel case was constructed with two single electrode TENG operating through the triboelectric mechanism between human skin and Polyethylene terephthalate(PET) film on the front part and Nitrile Butadiene Rubber(NBR) and PET film on the back part. This cost effective device was further tested by attaching with a cell phone at variable load frequency, airgap and finger combinations where the output response increased with the increased frequencies (60 to 240 BPM) and air gap (1cm to 5cm). Maximum output voltages of 14.8 V and 50.8 V were obtained for the front and back parts, respectively. Besides, maximum output powers were observed to be 3.78 W/m 2 at 0.46 MΩ and 6.21 W/m 2 at 1.02 MΩ, respectively. Also, the device was tested by integrating with conventional electronic components including capacitors, bridge rectifiers and 15 LEDs. Based on the results, a electrical circuit has been proposed to power touch cell phones. The device was further modified using Silver (Ag) nanoparticles in the front part. The modified TESTEC provided higher output response compared to the primary TESTEC. The TESTEC can be a self sustainable way to power touch electronic devices which can reudce the necessity to charge electronics devices in the conventional way.

“…Among them, the piezo‐, tribo‐, or thermoelectric approaches seem highly favorable, and are found in many flexible sensing systems due to their low‐cost materials, simple and ready energy input (e.g., pressure or heat from human body) readiness, and ease of integration into flexible sensors on a single chip. Employing those types of power render self‐powered sensors compact and flexible …”

A concise, although admittedly non-exhaustive, didactic summary is given of some of the main concepts and approaches related to recent advances and developments to enable autonomous detection and monitoring of the likelihood or existence of a health risk state in continuous and real-time modes. To give a comprehensive statement, different aspects of these advanced materials and related devices are presented and discussed, such as: flexible sensors used for non-invasive detection of health-related physiological markers; self-powered materials to enable extended usage periods by harvesting energy from body movement and temperature; and self-healing properties of the materials used on the wearable devices to enable extended usage periods if scratched or cut. The linkage of these advanced materials and technologies together is particularly specified. Some of the strong and weak points in the development of each wearable material/device are clearly highlighted and criticized. Several ideas regarding further improvement of skin-based wearable devices are also discussed.
