Wearable Health Devices are proving to be extremely helpful for people to keep a check on their health conditions. People can monitor their status at a fitness level and also at the proper medical level. With already a number of smart products in the market and the surge in the implementation IoT and AI in the healthcare sector, it is safe to say that the future lies in virtual healthcare and Wearable Health Devices. The cover photo of this October 2019 issue is inspired by the editorial article "Wearable Healthcare Devices", by Dr. Ashutosh Tiwari.

Use of fossil fuels to produce nitrogenous fertilizer contributes to global warming and climate change. The plasma activated water (PAW) provides an alternative option for nitrogen supply to plant by fixing the nitrogen available in the air into the water using plasma. The PAW is a mixture of nitrate, nitrite, and hydrogen peroxide as its major constituents. In this work, an attempt was made to generate PAW using an efficient and scalable PAW generator. Then plasma is characterized by measuring the power, and OES spectrum. This is a study in which for the first-time arc plasma has been used to demonstrate enhanced plant growth on tomato plant. The results indicate that compared to control, the plants fed with PAW activated for 30 minutes (PAW-30) have 1.5 times higher shoot length, 4 times higher leaf count and more than twice the chlorophyll content in the leaves. The wet weight of the plants fed with PAW-30 was 61% higher than that of the control. © VBRI Press.
