Abstract
An elongated pressure sensor includes an inner bar carried within an elongated hollow member. A gap formed between the bar and elongated hollow member changes shape in response to a pressure applied to the elongated hollow member. Capacitive electrodes on the elongated hollow member and bar have a capacitance which changes in response to applied pressure. The sensor is adapted for coupling to a multifunction body.
