Various implementations include force elements for electronic devices. In some aspects, a force element includes: an outer ring surrounding a central axis and having a first diameter; an inner ring surrounding the central axis and having a second diameter that is smaller than the first diameter; an outer wall connecting a radially inner portion of the outer ring with a radially outer portion of the inner ring; an inner wall extending from a radially inner portion of the inner ring and located radially inboard of the outer wall; and a central platform extending from the inner wall around the central axis.

Electronic device with force element

An induction cooking system with an induction heating system, a cooktop, and cool touch cookware that has a target that is heated by induction. An absolute cookware temperature is directly sensed at one or more locations of the cookware, for example at the target. A relative cookware temperature can be determined based on the value of an electrical variable of a circuit that includes the target. The cookware can include a layer of thermal insulation directly below and spaced from the target by a gap. The insulation and gap act as the major heat insulating elements to keep the outer surface of the cookware cool. This allows the induction coil to be placed just below the cooktop, without any insulation between the coil and the cooktop. The cooktop can be cooled by placing a cooling chamber just below the cooktop and drawing air through the cooling chamber. The induction coil can be located in the cooling chamber.

A cooking utensil for use with an induction cooktop having a cooktop surface and an induction heating coil. The cooking utensil has an inner wall made from an electrically conductive material, an outer wall made from an electrically non-conductive material, and a gap between the inner and outer walls. There is an intermediate wall in the gap. The intermediate wall divides the gap into an inner chamber between the inner wall and the intermediate wall and an outer chamber between the outer wall and the intermediate wall.
