SINGAPORE - The amount of electricity generated by our body can power a small LED lamp.

Scientists from the National Metrology Centre (NMC), Singapore's agency for weights and measures, will be demonstrating how it can become a "human battery" as part of the Singapore Science Festival's X-periment carnival.

The three-day event highlights the latest developments and research work, including innovations and experiments by local researchers.

To light the bulb, visitors to the festival simply need to place their hands on aluminium, copper and magnesium plates. The metal plates act as electrodes with the sweat from palms allowing the electric current from the human body to power the lamp, explained Dr Chua Sze Wey, principal metrologist at the centre, a research institute under the Agency for Science, Technology and Research.

 

"This is why those with sweatier palms will give out more current," he said.

The centre's booth will be at the X-periment carnival held from today to Sunday from 11am to 8pm each day at at Vivocity.
