Who is the inventor of the touch sensor?

The invention of the touch sensor is attributed to multiple contributors rather than a single inventor, as it evolved over time through various technological advancements. Early touch-sensitive devices date back to the 1960s, with significant developments by researchers like Dr. Samuel Hurst, who created the first resistive touch screen in the 1970s. Today, touch sensor technology encompasses various types, including capacitive and optical sensors, each developed by different inventors and companies.
