Sensonics International, whose headquarters are located in Haddon Heights, NJ, USA, was incorporated in 1982. The company was founded by Dr. Richard L. Doty, Director of the Smell and Taste Center at the University of Pennsylvania. Its initial product, the 40-odorant Smell Identification Test™, is the commercial version of the University of Pennsylvania Smell Identification Test (UPSIT). This widely used test was developed at the University of Pennsylvania as a result of funding from the National Institutes of Health. Since its founding, Sensonics has developed multiple taste and smell tests incorporating microencapsulation and other technologies.

Examples include the Pediatric Smell Wheel ® (PSW; 2003), the Self-Administered Computerized Olfactory Testing System (SCOTS; 2009), the Snap & Sniff ® Olfactory Test System (2015), the 4-item NHANES Pocket Smell Test (PST; 2014), the Self-Administered Lateralized Taste Test (SALT; 2018), the Waterless Empirical Taste Test (WETT®; 2018), a novel electrogustometer (2018).

To date, the Smell Identification Test has been translated into over 30 languages and has been employed in hundreds of published medical and research publications. Originally located in a 5,000 square foot facility, Sensonics expanded its primary manufacturing facilities in two new locations in 2018: a 10,000 square foot building located at 411 South Black Horse Pike in Haddon Heights, New Jersey, and a 6,000 square foot facility located at 629 Creek Road in Bellmawr, New Jersey.
