The inability for multi-touch technology unlike the capacitive touch sensors.Cost-effective and durable to be used in harsh environmentsĭisadvantages of a resistive touch sensor:.Older music players, game consoles, etc.The voltage changes are then compared to the starting voltage, allowing for the point at which the touch took place to be calculated.The outside conductive layer is then pressed against the inner layer, resulting in voltage changes.

The user applies pressure against the surface.Unlike the capacitive touch sensors, it’s not multi-touch compatible. It consists of two conductive layers and a non-conductive separator. Resistive touch sensor measures touch through responding to the pressure applied to their surface. Reliability concerns when used in harsh environments.It’s built on the glass itself, hence making force insignificant to sensing requirementsĭisadvantages of a capacitive touch sensor: Doesn’t require pressure to be applied since.

Portable devices such as smartphones and tablets (iPhones, iPad, etc.).

Multiple touchpoints can be detected as well, allowing for touch pinch and spread.It results in a decrease in capacitance and allows the system to determine the touchpoint.The printed circuit panel around the outer viewing area of the glass panel creates an electrical charge across the surface.The user applies touch on the glass panel.It consists of an electrode film on top of the glass panel that’s conductively coated with a printed circuit pattern around the outer viewing area. *Note: The following types of touch sensors can be referenced as touch technology too used on touch screens to enable your device to interpret and deliver your commands.Ĭommonly associated with MicroChip at42qt1010, a Capacitive touch sensor measures touch based on electrical disturbance from a change in capacitance. Hence, I’ll be introducing the two main touch sensor types with its working principle/usages! The above explanations of how a touch sensor work and its applications apply to a generic sensor, where there are still different type of touch sensor that works uniquely and is more applicable for certain applications. Most other applications that require pressure/distance measurement.Touch sensor faucet in kitchens allowing for control of running water without having to physically turn the knob.Smartphones, automotive, industrial applications.When the robot runs into something, the touch sensor can have it to stop moving) Touch sensor in robotics a touch sensor is commonly used in robots, enabling basic movement and the ability to detect touch in its surroundings (E.g.What is touch sensor used for? Key ApplicationsĪs mentioned in my introduction, a touch sensor is used for a wide array of applications, with those being: A touch sensor works like a switch, where when there’s contact, touch, or pressure on the surface of a touch sensor, it opens up an electrical circuit and allows currents to flow through it.
