1. A stylus for a touchscreen comprising:
a barrel extending in a longitudinal direction, the barrel comprising:
a first end comprising an opening and a second end, the first end and the second end being, in the longitudinal direction, opposite to one another, and
a first part and a second part, the first part including the first end and the second part including the second end;
a first electronic tip received at least in part in the barrel and configured to have at least an in-use configuration in which the first electronic tip protrudes from the first part of the barrel through the opening; and
an energy harvesting device comprising at least two of an energy harvesting element, a transducer, or an energy storage device, wherein
the energy harvesting element includes a piezoelectric element that is configured such that an electrical current is generated when the piezoelectric element is compressed by the first electronic tip,
the energy storage device stores electrical energy generated when the piezoelectric element is compressed via transmission of the electrical current through the transducer,
the energy harvesting element further including a coil and a magnetoresistive or magnetoelectric element, wherein the coil is positioned circumferentially around an exterior of the first electronic tip and the magnetoresistive or magnetoelectric element is operably connected to the coil and the transducer such that a current is induced through the coil when the coil is placed in proximity to an electronic or magnetic device, and the induced current is configured to be stored by the energy storage device via transmission of the current through the transducer, and
the energy harvesting element further comprises an antenna operably connected to the transducer and configured to receive radiofrequency waves and convert the received electromagnetic energy waves into a current, and
the stylus is configured to harvest electrical energy via the piezoelectric element, the magnetoresistive element or the magnetoelectric element, and by the antenna simultaneously.
