Fig. 4: Experimental demonstration of the fabricated drug delivery module in a benchtop setting.
From: A soft neural interface with a tapered peristaltic micropump for wireless drug delivery
a Optical image of the micropump-based microfluidic probe (scale bar: 5 mm). b Circuit diagram showing wireless functionality and micropump operation. c Real-time GPIO on/off pattern of a microheater controlled wirelessly, which directly modulates the flow rate of the drug delivery module. d Flow analysis results according to frequency changes in in-vitro experiments. e Results of flow per cycle according to switching frequency in in-vitro experiments (n = 3). Error bar represents the standard deviation. f Optical images of drug delivery over time in in-vitro experiments (scale bar: 1 cm).
