Nimbus EHD (ElectroHydroDynamic) spray is a form of electrospray – the name given to a certain kind of aerosol that is formed when electricity is used to disperse a liquid. High voltage is applied to a liquid supplied through an emitter. The liquid reaching the tip forms a Taylor cone, which emits a liquid jet. The surface of the jet breaks down to form small and highly charged liquid droplets, which are dispersed due to Coulomb repulsion.

– EHD droplets are uniform at the desired size, typically somewhere between 10 and100 microns (but can be smaller)
– EHD spray is able to cover target surfaces evenly due to mutual repulsion of each droplet
– EHD spray is capable of wrapping around the surface to cover both sides

One of the key features of the Electrodyn system was the use of low-cost carbon-impregnated conducting plastics to make a combined bottle/nozzle (Bozzle).The use of a pre-filled unit meant there was no need for the user to ever handle chemicals.

Taylor Cone

The Taylor Cone – a precondition of electrospray – exists when electrical pressure builds up on a semiconducting liquid. It was first observed by Sir Geoffrey Ingram Taylor in 1964.

The field-adjusting electrode

The field-adjusting electrode, invented by Dr R A Coffee, allowed for electrospray at greater widths and more control.

Electrodyn

ICI’s Electrodyn was a popular agri-sprayer for developing countries.

Pulmonary Inhaler

Medical Inhalers using EHD technology have been developed for asthma, cystic fibrosis and flu vaccines.

Electrospinning for woundcare

Spraying a collagen web impregnated with fibroblasts will form a scaffolding onto which new skin can grow without causing scars.
