Cypress Semiconductor Corp. (NYSE:CY) is offering a free online seminar that looks at the benefits gained from adding a capacitive sensing interface to an actual system design. The 60-minute webinar entitled “Using Capacitive Sensing to Solve Real-World Design Problems” will be presented on Wednesday, March 26 at 9:00 a.m. PDT.
The presenters will give a detailed analysis of the design of an ice-hockey skate blade from Therma Blade, Inc., which uses heat to reduce friction between the blade and the ice surface. Cypress’s PSoC® CapSense(tm) solution allows the heat to be turned on and off using touch sensitive controls. The seminar will show how capacitive sensing solves the challenges of designing a switch that is water-resistant, durable, low-power, reliable, low-cost and can be easily assembled for high volume production.
Capacitive sensing detects the presence or absence of a conductive object, like a finger. A single capacitive sensing device can replace dozens of mechanical switches and controls with an elegant touch-sensitive interface. The solution supports touch screens and proximity sensing for superior product differentiation. Capacitive-sensing-based “button” and “slider” controls are more reliable than their mechanical counterparts because they are resistant to environmental wear and tear, temperature change and moisture. Capacitive sensing can be used as a replacement to membrane switches and it also works with a variety of non-conductive overlay materials of varying thickness.
The webinar will cover how an on-off switch was implemented in an ice-hockey blade using capacitive sensing. It will show how capacitive sensing solves the challenges of designing a switch that is:
- Water resistant
- Capable of withstanding high impact
- Low power
- Low cost
- Has easy final assembly for high volume production
