TOOL RECOGNITION SYSTEM WITH IMPEDANCE SENSING FOR DENTAL DEVICES

A dental tool detection system for detecting a type of a dental tool attached to a dental device for performing a dental procedure includes a controller. The controller has an electronic processor and a memory electrically connected to the electronic processor. The system includes a motor control electrically connected to the electronic processor and electrically connected to a motor, and an electrical property sensor electrically connected to the electronic processor. The electronic processor is configured to (1) receive, from the electrical property sensor, a measured value of an electrical property associated with the dental device without the dental tool attached and separately a measured value of the electrical property of the dental device with the dental tool attached. The electronic processor determines a value of the electrical property associated with the dental tool, and recognizes the type of the dental tool based on the value. The electrical property is one or more of impedance, inductance, capacitance, and resistance.
