Sonicare electric toothbrush

Sonicare is an electric toothbrush manufactured by Philips.In 1987, David Giuliani, an entrepreneur with a background in electrical engineering, met with University of Washington professors Drs. David Engel and Roy Martin. They formed a new company named GEMTech to promote a dental hygiene device using a piezoelectric multimorph transducer. After several years of research and creating prototypes, the Sonicare toothbrush was introduced in November 1992 at a periodontal convention in Florida.

In 1995, GEMTech changed its name to Optiva Corporation. In October 2000, Philips Domestic Appliances and Personal Care, a division of Philips, acquired Optiva Corporation. A few months later Optiva Corporation changed its name to Philips Oral Healthcare, Inc. By the end of 2001, Sonicare had become the number-one selling rechargeable power toothbrush in the United States.[1]
