Destined to replace traditional aerosol and trigger-spray technologies in consumer, drug delivery and pharmaceutical applications, TTP’s patented TouchSpray™ technology uses a low-cost microdevice to generate precisely controlled droplets from bulk liquids without the use of propellants.

Innovative aerosol products will be packaged in compact new shapes and sizes thanks to the highly adaptable TouchSpray™ technology, which enables efficient delivery of concentrated liquids and suspensions from an un-pressurised reservoir.

Electronic control provides precise and consistent droplet size and creates a spray plume with a flexible format, making the technology suitable for a wide variety of applications. It has already been proven in the medical sector for nebulisers.

The technology is based on a vibrating perforated membrane – a low profile piezoelectric actuator incorporating a thin, perforated, stainless steel membrane, manufactured using a patented micro-machining technique to produce an array of precision, micron-sized nozzles. The actuator is driven at ultrasonic frequencies, causing the membrane to vibrate, ejecting millions of precisely sized droplets each second.
