A prototype of an advanced battery to demonstrate the presence of 3D printed silver flake electrodes that generate energy after coming into contact with sweat. The battery adheres to a sweat-absorbing and highly elastic cloth that is further linked to a wearable device such as a wrist band, watch, or arm strap. The dimensions set for the novel battery are 2×2 cm and would appear like a paper bandage. The researchers’ team from NTU Singapore verified its technology by imitating situations using artificial human sweat to show how it could supply energy for wearable electronic devices. Unlike traditional batteries, which are usually derived through eco-hazardous resources, the exclusive battery does not contain poisonous chemicals or heavy metals.
The invention of the sweat-powered battery highlights NTU's dedication to discovering pragmatic solutions to curb the detrimental effects of hazardous waste on the environment by offering a more sustainable option. This is among the four leading challenges that humanity has been facing so far. The NTU battery is constructed by printing silver flakes and hydrophilic poly ink onto a stretchable textile, which serves as electrodes. The chloride ions and acidity in sweat urge the silver flakes to form a clump, thereby boosting their ability to conduct electricity. As the reaction proceeds, the electric current begins to flow between the electrodes.
As the stretching occurs, the resistance of the battery material goes on decreasing. During exercises and HIIT, the battery would be under strain offering negligible resistance. As the stretchable cloth is a good absorbent, it holds a significant volume of sweat compared to the size. The reservoir would make sure that the battery remains fuelled even when the rate of sweating varies. As the secretion rate of human sweat varies depending on the location, body type, and weather conditions, this is critical to design the battery technology that generates ample energy to power the connected wearables. The researchers intend to investigate the impact of other components of human sweat, as well as how elements such as body heat may affect the battery's efficiency.
