Special Issue Information

Dear Colleagues,

The development of self-powered storage/sensor (SPS) devices is the forthcoming revolution in smart technology, which makes it possible to abolish the use of complex battery sources, external circuit components and natural sources used for energy generation. In the recent decade, SPS gained great attention and broadly diversified into electronic, chemical, biomedical and security sectors. The growth of SPS technology advanced through the prototypes of nanostructures, energy conversion approaches, storage techniques and multi-sensing methods. Recently, the design and development of self-powered storage device (either internally or externally driven) is an area of emerging research interest, having an inter-relation between the energy storing electrode and electrolytes via choice of effective performances of capacitive electrode materials, electrolytes (liquid or gel-type, and solid), with dual functional separators which provide new-energy conversion/storage processes, such as piezo-electrochemical (piezo-ionic, mechano-ionic) and photo-electrochemical (photo-capacitive electrodes, photo-redox electrolyte).

Modern technology is widely reliant on the adaptable, battery-less, cost-effective, longer lifetime of self-powered sensors that can monitor/sense various stimuli, such as chemical, gas, biological (enzymatic/non-enzymatic) and implantable sensors. These sensors/storage units are powered by various energy generating approaches like piezoelectric, triboelectric, thermoelectric, pyroelectric and magnetic effects etc. Furthermore, synergistic principles, innovative working mechanisms, efficient performances and device designs that are adaptable in harsh environments are highly effective for SPS.

This Special Issue on “Self-powered storage and sensors” aims to provide an overview of new hybrid energy conversion and storage/sensor systems and insights on innovative conceptual designs of next-generation SPS via (i) cost-effective growth methods for harvesting /sensing/capacitive nanomaterials, (ii) novel interface engineering between the harvester with storage/sensor compartments and (iii) theoretical/experimental studies on energy-conversion efficacy and sensing performance. We cordially invite you to submit manuscripts on the significant role of multifunctional nanostructures, efficient device prototypes for self-powered storage, and adaptable self-powered sensors. We are glad to welcome contributions on the above-mentioned subjects from scientists, academic researchers and those involved in related industries across the globe.

Self-powered piezoelectric-biosensing textiles for the physiological monitoring and time-motion analysis of individual sports have been developed. The material system is composed of tetrapod-shaped ZnO nanowires on common textiles. The mechanism is based on the coupling of enzymatic reaction (LOx and lactate) and piezoelectric effect. After conformably attaching the device to the athlete, the device can monitor in real-time the moving speed, frequency, joint angle, and sweat lactate concentration of the athlete. The whole monitoring/analysis process is battery-free. The motor skills and physiological state of two athletes are investigated using the textiles, and different lactate threshold times and maximum lactate release capacities have been obtained. This technique can help them develop distinct training programs. This research is a new direction for the scientific monitoring of kinematics and may also stimulate the development of self-powered wearable sports-related systems. Full article

A triboelectric nanogenerator-based self-powered resonant sensor is proposed and investigated. By integrating an inductor and a microswitch with a triboelectric nanogenerator, a new type triboelectric nanogenerator is obtained, the pulse voltage output is converted to an oscillating signal with a very stable modulated resonant frequency, immune to the cross disturbance of contact-related variation (force, frequency, distance) and environmental variation, such as humidity and temperature. This is utilized for non-destructive defect detection. When the coil inductor scans the surface of a specimen with defects, varying resonant frequencies are obtained for different types of defects, showing excellent consistency between the experimental and simulated results. The results demonstrate the potential of the self-powered TENG-based resonant sensor to be a highly stable and sensitive magnetic sensor for the non-destructive defect detection applications.
