Researchers have taken a step forward in developing a new armband that can track the heart’s electrical activity without requiring bulky wiring or sticky gel on the skin.
Specifically, they determined the ideal placement for three electrodes in the band design, and how tightly the band needs to be to best detect electrical signals from the heart.
The findings are the latest advance in a multi-institutional effort to develop an armband that takes electrocardiogram, or ECG, measurements in order to track heart rate. Researchers ultimately envision a device that could be worn as an arm sleeve throughout the day. Energy from body heat or movement would supply the power.
The Horned Lizard Conservation Society, a nonprofit that sponsors scientific research on the critters, started in 1991. Speaking at one of its first meetings was Wade Sherbrooke, the former director of the Southwest Research Station of the American Museum of Natural History in Arizona. He was moved by people’s passion about the creatures he’d studied for more than 40 years.

“Some old rancher would get up and say, ‘We
had horny toads and we should have them again! Ice cream cones and horny toads, that’s what life’s all about!’” he recalled.

he said, is just one tragic example of the damage humans have inflicted on this ever-warming planet.
