Abstract
A sensor for installation on a steering wheel includes a pressure sensitive material mounted on a base material of the steering wheel. The pressure sensitive material is configured to provide an electrical signal to a controller when pressure is applied. The controller provides a command to a vehicle system based on the electrical signal. The pressure sensitive material has at least one of a variable resistance and a variable capacitance based on the amount or type of pressure that is applied to the material. The electrical signal is based on the at least one of a variable resistance and a variable capacitance.
