A thin strip as shown in the image seems nothing more than a chip but this sweat-fueled device is very handy. As per the paper published in Joule, the device can harness 400 millijoules of energy in 10 hours irrespective of the task you do.
This much energy can fuel a wristwatch for at least 24 hours.

The sweat-powered wearable is only 1-cm in size and is made using simple electronic components that fit perfectly on the small chip. It is built from the piezoelectric material, electric conductors, capacitors, and enzyme-based electrodes.
The user can easily wrap the device around his/her fingertips and perform day-to-day tasks. The carbon foamed conductors will absorb the sweat from the fingertips. A chemical reaction takes place that converts sweat into electricity which then gets stored into the in-built capacitor.
The wearer can use the energy as per their need.
