Wearable exoskeletons are electro-mechanical systems designed to assist, augment, or enhance motion and mobility in a variety of human motion applications and scenarios. The applications, ranging from providing power supplementation to assist the wearers to situations where human motion is resisted for exercising applications, cover a wide range of domains such as medical devices for patient rehabilitation training recovering from trauma, movement aids for disabled persons, personal care robots for providing daily living assistance, and reduction of physical burden in industrial and military applications. The development of effective and affordable wearable exoskeletons poses several design, control and modelling challenges to researchers and manufacturers. Novel technologies are therefore being developed in adaptive motion controllers, human-robot interaction control, biological sensors and actuators, materials and structures, etc.

Wireless Power Transfer (WPT) enables power to be transferred from a grid or storage unit to a device without the need for cable connections. This can be performed by inductive coupling of magnetic fields as well as by direct radiative transfer via beams of electromagnetic waves, commonly radiowaves, microwaves or lasers. Inductive coupling is the most widely used wireless technology with applications including charging handheld devices, RFID tags, chargers for implantable medical devices, and proposed systems for charging electric vehicles. Applications of radiative power transfer include solar power satellites and wireless powered drone aircraft.

Writing As a Human Activity offers a collection of original essays that attempt to account for Charles Bazerman’s shaping influence on the field of writing studies. Through scholarly engagement with his ideas, the 16 chapters—written by authors from Asia, Europe, North America, and South America—address Bazerman’s foundational scholarship on academic and scientific writing, genre theory, activity theory, writing research, writing across the curriculum, writing pedagogy, the sociology of knowledge, new media and technology, and international aspects of writing. Collectively, the authors use Bazerman’s work as a touchstone to consider contemporary contexts of writing as a human activity.
