ResoSight Information

Ondova makes every device worn on the ear understand the person wearing it. Earbuds and headphones sit on one of the best places on the body for continuous sensing, yet very few of them know anything about their wearer. Adding that awareness today usually means adding dedicated sensors, along with the cost, power, board space and integration effort they bring. Ondova turns the speaker already at the ear into the sensor. A speaker's response changes slightly with the ear around it and with small movements such as a heartbeat or a tap. A compact analog front end in the driver path reads those changes, even while music plays. Ondova's physics-informed AI software then turns them into features: wearer identification, heart rate, wear detection, and tap and gesture control. Nothing optical, capacitive or inertial is added to the device. The technology works across in-ear, on-ear and over-ear products, from earbuds and headphones to communication headsets and hearing devices. Device makers license it through an SDK and the design of the sensing circuit, and new capabilities arrive as software on the same hardware. Based in Montréal, Ondova is part of the TandemLaunch portfolio.
