TORSIONAL HINGE BIAS TO PROVIDE BISTABILITY WITH ZERO FLUID PRESSURE UNDER IMPACT FLUIDIC DRAG FORCE SWITCHES TO CLOSED OR OPEN CHANNEL POSITION BY AN INSTANTOR OR STEADY IMPACT FLUIDIC FORCE c STOP OPEN CHANNEL CLOSED CHANNEL Schematic and prototype of a magnetic flux densitybased circuit breaker showing the onoff switching of fluid flow Flow in the bent fluid channel results in open channel fluid drag force to form a compact magnetic circuit which in turn generates a magnetic flux density to provide a force which opposes the drag force The straight channel fluid drag force on the wire momentum provides a counterbalance force with the magnetic force as well as the bias force from the elastic hinge and results in bistability and switching states This device performs as fluidic circuit breaker with two stable switching states ie a open fluid channel state and b closed fluid channel state Under zero fluid pressure the device is magnetically bistable with the magnetic force serving as a counterbalance to fluid drag force in the elastic bias hinge to maintain the channel at either open or closed switching states Under impact fluid pressure the device acts as a fluidic circuit breaker as the impact flow rapidly actuates the device to open or close channel switching orientations with the fluid drag forces and magnetic force counterbalance dictates switching orientation Switching can be initiated due to steady or instant flow impact Concept is to reduce the actuation fluid pressure required to achieve switching using magnetic counterbalance of fluid drag force in the elastic bias element Minimizing the actuation fluid pressure facilitates circuit breaker operation at ultralow fluid pressures This fluidic circuit breaker concept significantly advances lowpower fluidic device actuation by using a magnetic flux densitybased magnetic force counterbalance acting against fluid drag force used to achieve bistability This enables ultralow fluid pressure actuation of fluidic circuit breakers for applications in fluidic circuits and fluid actuation systems The fluidic circuit breaker provides a step towards enabling magnetic forcebased ultralow power fluidic devices including switches latches and transistors for fluidic computing systems with low fluid pressures 20230629
