The hybrid hydrogel can respond to both heat and electrical stimuli, and can be directly printed layer-by-layer using a commercial 3-dimensional printer, without requiring any curing. The hybrid ink is printed onto a transparent, flexible conductive electrode composed of silver nanoparticles and ...
3.2. Printed optoelectronic devices and sensors Optoelectronic devices such as solar cells, and LEDs can be fabricated on curved and flexible substrates for wearable and healthcare devices. However, several challenges such as the deposition of thin uniform layers and the intermixing of materials that ...
The dramatic advances in flexible/wearable electronics have garnered great attention for touch sensors for practical applications in human health monitoring and human–machine interfaces. Self-powered triboelectric tactile sensors with high sensitivity, reduced crosstalk, and simple processing routes are highl...
