An international team of researchers (China, Canada) has developed a moisture energy harvesting device based on strongly hydrophilic TiO2 nanowire networks (TDNNs) containing 3D nanochannels. Electricity is generated from the diffusion of water molecules through the many 3D nanochannels in the TDNN. They have demonstrated that the device can yield an output power density of up to 4 µW cm−2 when exposed to a highly moist environment. The new type of device is successfully used as self‐powered wearable human‐breathing monitors and touch pads… read more. TECHNICAL ARTICLE
