HIGHLIGHTS
- who: January and collaborators from the University Birmingham, United Kingdom have published the paper: Electrically driven heartbeat effect of gallium-based liquid metal on a ratchet, in the Journal: (JOURNAL)
- what: We designed an asymmetrical sawtooth-structured substrate to improve the manipulation of liquid metal heartbeats with a frequency range that is two times that of the smooth surface, ranging from 2.7 to 4.8 Hz.
- how: To investigate the effect of different substrates the authors conducted eGaIn drop heart beating on a flat surface and ratchet substrates in three directions .
