Make your products audibly and

noticeably better with GREWUS components

Acoustic signal sensores and haptic actuators are being installed in an increasing number of machines, systems, and devices. They warn, remind, inform, give users feedback on operation, and help people find their way in everyday life.


At GREWUS, we develop and produce innovative acoustic signal sensores and haptic actuators for all industries and applications. You will find our products in many vehicles and industrial plants, in the office, in the household, and even in medical technology. You probably have already come into contact with our signalling devices, because we are one of the market leaders in our field worldwide. We also develop and manufacture suitable solutions for your products, always tailored to your requirements and with “sensible” added value for you and your customers.
