"gallium-based droplets convert digital signal to analog signal using pulse-width modulation controls... oxidized and reduced mimicing neuron hyperpolarization and depolarization.. low voltage liquid metal oxidizes corresponding to high-resistance (1), reversing voltage polarity returns metal to low-resistance (0)... 8 storage units FlexRAM 1 byte array... retains data 12 hours, >3,500 cycles... droplets Ecoflex encapsulated... memory element sizes from mm to nm droplets... smaller more sensitive memory response"
