Performance of photonic devices critically depends upon their efficiency on controlling the
flow of light therein. In the recent past, the implementation of plasmonics, two-dimensional …

Origami, the art of paper folding, addresses traditionally conflicting requirements for
designing both powerful and low-cost haptic interfaces. As of today, there are no …

Multifunctional sensors find widespread applications in wearable healthcare, Internet of
Things (IoT), environmental monitoring, and human–machine interactions, yet they suffer …

Safety has always been a concern for underground miners or construction site workers in
general. The recent growth of the Internet of Things (IoT) and its applications has paved the …

The next-generation wearable devices require highly stretchable and stable conductive
electrodes. Accordingly, in this study, kirigami patterned silver electrodes were designed …

This work reports a novel microneedle-based leaf patch for real-time monitoring of sap pH
levels, which is an early indicator of stress levels in plants. The leaf patch was interfaced …

Flexible strain sensors have great potential in wearable applications, yet it is challenging to
achieve the desired sensitivity, stretchability, reversibility, durability, and skin conformity …

This work presents a hybrid sensor suite comprising a microneedle-based multiplexed
hormone sensor and a volatile organic compound sensor integrated on a single chip. The …

This work reports a kirigami-shaped sensor interfaced with an internet-of-things platform for
strain insensitive and real-time temperature detection. The performance of the sensor was …

This study introduces StressFit, a novel hybrid wearable sensor system designed to
simultaneously monitor electromyogram (EMG) signals and sweat cortisol levels. Our …
