Grip pressure is monitored by a collection of battery powered components embodied in an assembly analogous to an ordinary wrist watch, that is a watch housing or casement and a stretchable band. The system, which we shall refer to as a swing monitor, is worn on the wrist and deployed in such a way that the back of the housing or casement is cinched securely to the back or underside of the wrist. A pressure plate on the back of the watch makes contact with the pulse region of the wrist. The flexing and relaxing of the muscles and tendons of the wearer is read by an electronic pressure sensing device, a piezo sensor. A tighter grip will register greater pressure and a looser grip, less pressure. The device records grip pressure associated with the swing of a golf club, tennis racquest or baseball bat, among other articles of sports equipment meant to be swung. The grip pressure determined to be optimal, that is giving the desired result, can be SAVED in the memory of the swing monitor system. Subsequent swings and their associated grip pressures are compared with the SAVED value of the optimal or best swing. An audible signal alerts the wearer if the grip pressure departs from that registered on the optimal or best swing.
