Nano-enabled paper humidity sensor for mobile based point-of-care lung function monitoring

Fast-response humidity sensor based on laser printing for respiration monitoring

“…A variety of advanced respiration monitoring devices have been developed for health monitoring and medical diagnosis. 4 Although the traditional respiration monitoring devices are generally functional, their portability and expenses are still challenges. Therefore, the design of epidermal real-time monitoring devices has broad application prospects.…”

NFC based Polymer Strain Sensor for Smart Packaging

“…The safety of goods during transportation is a key step particularly for food packages, as even slight damage could raise health and safety concerns [1]. For this reason, several types of sensors such as pH [2,3], biomolecules [4][5][6], humidity [7], VOCs [8,9] etc. have been explored with self-powered or power storage means such as supercapacitor and battery.…”

Microfluidic Schottky-junction photovoltaics with superior efficiency stimulated by plasmonic nanoparticles and streaming potential

“…In recent times, a rapid progress in the micro and nanoscale technologies has enabled the development of next generation energy harvesters suitable for use in mobile phones, calculators, healthcare devices, laptops, computers, and sensors. [1][2][3][4][5][6][7] The economic, scalable, procient, and eco-friendly technologies are envisaged to be able to harvest high-density power from the various naturally abundant resources. [1][2][3] Arguably, this journey started about a hundred years ago with the inventions of the photovoltaic effect, 8,9 solar cells, 10 and the photoelectric effect, 11,12 which initiated the pathways to convert solar energy into electrical power with usable efficiencies.…”
