World’s first working liquid RAM FlexRAM developed
By ForGeeks Scientists from Tsinghua University have reported their new achievement — the creation of liquid-metal RAM, dubbed FlexRAM. According to the developers, this represents another major breakthrough in the development of flexible electronics and a new generation of implants.

The novelty is shown in the photo below as molten gallium metal embedded in a flexible biopolymer called Ecoflex. By applying electrical pulses, the metal is oxidized or reduced, causing it to change its resistance and switch between “1” and “0” states, corresponding to binary values.

The developed prototype includes 8 independent 1-byte FlexRAM cells capable of storing information for up to 12 hours without power supply. More than 3,500 write cycles have been performed during experiments, although this figure is still insufficient for commercial use. However, scientists are continuing to improve the technology and have plans to —reduce the size of the metal droplets to the nanometer scale, which will increase the memory density.

The resulting invention could potentially be used in the creation of flexible robots that can change their shape as needed, as well as in brain-computer interfaces and implantable or wearable electronic devices.
