Echo Therapeutics, Inc. (ECTE) develops non-invasive, wireless continuous glucose monitoring (CGM) systems and transdermal skin permeation technologies for diabetes management, wearable health consumer applications, and hospital critical care settings; its core products include the Symphony CGM system, comprising a needle-free skin preparation device, transdermal glucose sensor, battery, and wireless transmitter for on-demand glucose data extraction and delivery of topical pharmaceuticals. Founded in 1989 and headquartered in Iselin, New Jersey, the company targets outpatient diabetes markets, fitness and lifestyle sectors, and medical facilities with operations supported by licensing agreements, including partnerships with Ferndale Pharma Group for skin preparation devices across North America, the UK, South America, Australia, New Zealand, Switzerland, and parts of Europe; Handok Pharmaceuticals for CGM in South Korea; and Medical Technologies Innovation Asia for CGM development, manufacturing, and commercialization in China, Hong Kong, Macau, and Taiwan. Although no major acquisitions, funding rounds, or product launches have occurred in the last 1-2 years, the company maintains its focus on advancing needle-free biosensing platforms amid a near-zero stock valuation as of late 2025, with historical financing such as a $5.1 million convertible notes and warrants placement in 2016 supporting research, development, and general corporate purposes.
