SINGAPORE — Researchers in Singapore have found a way of controlling a Venus flytrap using electric signals from a smartphone, an innovation they hope will have a range of uses from robotics to employing the plants as environmental sensors.
Luo Yifei, a researcher at Singapore’s Nanyang Technological University (NTU), showed in a demonstration how a signal from a smartphone app sent to tiny electrodes attached to the plant could make its trap close as it does when catching a fly.
“Plants are like humans, they generate electric signals, like the ECG (electrocardiogram) from our hearts,” said Ms. Luo, who works at NTU’s School of Materials Science and Engineering.
“We developed a non-invasive technology to detect these electric signals from the surface of plants without damaging them,” Ms. Luo said.
The scientists have also detached the trap portion of the Venus flytrap and attached it to a robotic arm so it … Read the rest
