Neonode Inc. announced it is expanding its line of touch sensors. Neonode has established its line of sensor modules as the go-to component for adding touch input, on any surface and in-air, to new and existing products. This new type of touch sensor is intended to be mounted on the side of the touch surface - enabling new levels of design freedom and allowing for integration in a wider range of applications. The new touch sensors are available at digikey.com in nine lengths, to support interaction areas from 3" to 16" diagonally.
