Zytronic has announced that its Zytouch touch sensor product has been deployed by JCDecaux in some of its Cyclocity urban bike hire schemes.

The French firm has already rolled out several services across France and abroad, taking advantage in some cities of the durability and low-maintenance requirements offered by Zytronic's Projected Capacitive Technology (PCT).

Cyclocity is a self-service bike-rental system offered through collaboration between JCDecaux and cities.

In some cases, it employs a Zytouch-equipped kiosk located next to a rack of bikes, allowing users to book rentals, specify their bike preferences and validate their identity via a touch screen.

Zytronic's PCT senses touch by detecting small capacitance changes in a set of microfine electrodes deposited in an XY grid array and embedded within a laminated construction behind a protective front surface.

Since the electrodes can sense the capacitance changes at up to 20mm below the surface, they are protected against any accidental or deliberate damage, heat, surface contaminants and scratching.

PCT does not suffer from the problems of drift encountered with some alternative technologies, thus eliminating the need for touchscreen recalibration during the display lifetime and substantially reducing maintenance costs.

As well as providing unrivalled robustness, PCT touch sensors may be operated with gloved and ungloved fingers and affords better sunlight readability than the metallic coating based touch screen solutions, which tend to reduce the amount of light transmitted from the screen.

As well as providing basic identity validation and user input facilities, the 10.4-in Zytouch-based touchscreens used for Cyclocity provide a variety of auxiliary information, such as local area maps, and lists of bikes available at neighbouring sites.

Users can also access their account details and subscription information.
