<p>A touch panel and an electronic device are provided. The touch panel includes a first substrate; a second substrate that is spaced apart from the first substrate by a gap and includes a contact surface; driving electrodes that are formed on each of the first substrate and the second substrate; and electro-rheological fluid that is disposed in the gap. When a driving voltage is applied between the driving electrodes, a button area is delimited due to a variation in viscosity of the clcctro-rhcological fluid at the button area. When a thickness of the gap is reduced to a value equal to or less than a threshold due to a pressing force applied to the contact surface at the button area, the driving voltage is cut off.</p> |
