When you tap, bend, or vibrate the disc, the ceramic material experiences mechanical stress, which causes an internal shift in electrical charges. This results in a voltage spike across the two wires. The harder the impact, the higher the voltage produced.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e \u003cbr\u003e\u003cstrong\u003eWhy the 35mm Disc is a Project Essential:\u003c\/strong\u003e \u003cbr\u003e• Self-Generating (Passive): It requires zero power to \"listen\" for vibrations. This makes it incredible for low-power or battery-operated projects that need to \"wake up\" only when an impact is detected. \u003cbr\u003e• Dual-Purpose (Sensing \u0026amp; Sound): While it is an excellent vibration sensor, it can also act as a buzzer. If you apply an oscillating electrical signal to it, the disc will vibrate and create sound. \u003cbr\u003e• Ultra-Thin Profile: At less than 1mm thick, it can be hidden under surfaces, taped inside a drum, or even placed inside the sole of a shoe to track footsteps. \u003cbr\u003e• Extreme Sensitivity: 35mm is a relatively large diameter for a piezo disc, which increases its surface area and makes it highly sensitive to even subtle vibrations or distant knocks.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e \u003cbr\u003e\u003cstrong\u003eTechnical Capabilities:\u003c\/strong\u003e \u003cbr\u003e• Voltage Output: A sharp knock can produce a spike of over 10V to 50V. While the voltage is high, the current is extremely low. \u003cbr\u003e• Fast Response: It reacts in microseconds, making it ideal for detecting high-speed events like a ball hitting a target or a glass breaking. \u003cbr\u003e• Durability: With no moving parts to wear out, these sensors can withstand millions of taps and vibrations.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e \u003cbr\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e \u003cbr\u003eThe 35mm piezo is the gold standard for knock-activated locks, electronic drum pads, security alarms (glass break detectors), and energy harvesting experiments (turning footsteps into milliwatts of power). \u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"TinkEdge","offers":[{"title":"Default Title","offer_id":46397452845255,"sku":"TE-LOADC-064","price":25.68,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6620\/6407\/files\/Piezoelectric_1.png?v=1776774062","url":"https:\/\/shop.tinkedge.tech\/products\/piezoelectric","provider":"TinkEdge","version":"1.0","type":"link"}
