Abstract: The bioelectrical impedance measurement device mainly includes a portable casing, a control member inside the portable casing, and an electrode assembly joined to the portable casing and electrically connected to the control member. The control member includes current generation element, a current collection and processing element, and a current protection element. The electrode assembly includes a left-hand contact and a right-hand contact, both configured on the portable casing. The electrode assembly further includes a left-foot contact, and a right-foot contact, both extended from the portable casing. The left-hand contact, right-hand contact, left-foot contact, and right-foot contact are respectively connected to a user's left hand, right hand, left foot, and right foot. The current generation element generates an electrical current, which enters the user's body through the limbs and then collected to calculate various bioelectrical impedances and to determine a required biological information.

Abstract: A grip-strength device with detection function comprises: a grip-strength assembly comprising a first supporting piece, a second supporting piece, a rebounding element, a plurality of detection elements, a circuit element, a pull-force measuring element, and a power-supply element. The user can hold the grip-strength assembly and press the first supporting piece and the second supporting piece; and the force given by the user to the first supporting piece and the second supporting piece is measured by the pull-force measuring element; thereby detecting the user's grip force; or touching the detection elements with both hands, the circuit element will generate the detection current to enter the human body through the detection elements and then returns to the circuit element to detect the muscle mass in the human body; thereby the grip-strength assembly can have the functions of simultaneously detecting the grip strength and the body's muscle mass.
