“…In particular, the first demonstration of a system exploiting six IMESs in a transradial amputee was recently presented 15 . Nonetheless, IMESs are active electronic devices which require a power supply through a wireless inductive coupling having a low power transfer efficiency 16 , 17 . In fact, the system that is currently in human clinical trials uses 70% of the prosthesis battery capacity to generate the electromagnetic field for wireless power coupling to the implanted sensors 15 , 17 .…”

Upper limb amputation deprives individuals of their innate ability to manipulate objects. Such disability can be restored with a robotic prosthesis linked to the brain by a human-machine interface (HMI) capable of decoding voluntary intentions, and sending motor commands to the prosthesis. Clinical or research HMIs rely on the interpretation of electrophysiological signals recorded from the muscles. However, the quest for an HMI that allows for arbitrary and physiologically appropriate control of dexterous prostheses, is far from being completed. Here we propose a new HMI that aims to track the muscles contractions with implanted permanent magnets, by means of magnetic field sensors. We called this a myokinetic control interface. We present the concept, the features and a demonstration of a prototype which exploits six 3-axis sensors to localize four magnets implanted in a forearm mockup, for the control of a dexterous hand prosthesis. The system proved highly linear (R2 = 0.99) and precise (1% repeatability), yet exhibiting short computation delay (45 ms) and limited cross talk errors (10% the mean stroke of the magnets). Our results open up promising possibilities for amputees, demonstrating the viability of the myokinetic approach in implementing direct and simultaneous control over multiple digits of an artificial hand.

“…The devices resonate when the resonant frequency is matched to that of the TX system. This results in more efficient energy harvesting [ 30 , 31 , 32 ]. Moreover, the dual coil TX system offers high quality (Q) factors compared with the modest Q factor of the single-coil TX system ( Figure 4 a) [ 29 , 33 ].…”

Wireless optoelectronic devices can deliver light to targeted regions in the brain and modulate discrete circuits in an animal that is awake. Here, we propose a miniaturized fully implantable low-power optoelectronic device that allows for advanced operational modes and the stimulation/inhibition of deep brain circuits in a freely-behaving animal. The combination of low power control logic circuits, including a reed switch and dual-coil wireless power transfer platform, provides powerful capabilities for the dissection of discrete brain circuits in wide spatial coverage for mouse activity. The actuating mechanism enabled by a reed switch results in a simplified, low-power wireless operation and systematic experimental studies that are required for a range of logical operating conditions. In this study, we suggest two different actuating mechanisms by (1) a magnet or (2) a radio-frequency signal that consumes only under 300 µA for switching or channel selection, which is a several ten-folds reduction in power consumption when compared with any other existing systems such as embedded microcontrollers, near field communication, and Bluetooth. With the efficient dual-coil transmission antenna, the proposed platform leads to more advantageous power budgets that offer improved volumetric and angular coverage in a cage while minimizing the secondary effects associated with a corresponding increase in transmitted power.

“…This article proposes the wireless power transfer of a prosthetics hand, one of the most common artificial limbs used among the physically disabled population. Published research in wireless power and data transfer techniques for prosthetic limbs is relatively scarce [4], [9], [10]. In [4], a fully wireless EMG recording system for upper limb prosthesis control is presented.…”

This article presents the design, manufacture and test of an inductively coupled wireless power transfer (WPT) system used as a power source for prosthetic hands. Prosthetic hands are the most common artificial limbs among the physically disabled population. Limited storage capacity of the battery places severe limitations regarding the continuous use of this device. A WPT link is therefore proposed to supply power to such devices. The WPT system consists of a transmitter circuit (class-E power amplifier) and WPT coils along with commercially available receiver circuit and multiple motors. Assessment of the unwanted heating of the human tissue due to wireless power transfer was simulated using the commercial electromagnetic simulator ANSYS HFSS TM . Results were experimentally validated by measuring in real-time temperature variations inside a phantom mimicking the properties of human muscle. Monitoring and control the rotation of the prosthetic hand was also demonstrated utilizing rotation-dependent wireless power transfer parameters. The WPT scheme proposed serves therefore the dual property of providing power to the prosthetic limb whilst monitoring the wrist rotation.
