Abstract: A band, or bracelet, is semi-permanently attachable to, and wearable about, a limb of the human body. The limb band is in the physical form of a familiar, and well-accepted, flexible plastic hospital-type wrist bracelet. As well as providing a physical platform to attach, and to mount, any of a large number of diverse portable electronic physiological, motion and like sensors of the human body and its condition, the limb band houses, and electrically connects, any of (1) a battery that is preferably rechargeable, (2) a solar cell for recharging the battery, (3) an antenna, and/or (4) a universal electronic signal connector (such as a miniature USB connector port). In this manner the limb band economically serves as a universal platform for mounting, supplying power and/or abetting wireless and wired communication to and from, wearable electronic sensors and monitors of humans and animals.
