Magnetoelectric Materials for Miniature, Wireless Neural Stimulation at Therapeutic Frequencies
Amanda Singer,Shayok Dutta,Eric Lewis,Ziying Chen,Joshua C. Chen,Nishant Verma,Benjamin W. Avants,Ariel K. Feldman,John O’Malley,Michael Beierlein,Caleb Kemere,Jacob T. Robinson +11 more
TL;DR: It is shown that an alternative wireless power method based on magnetoelectric (ME) materials enables miniature magnetically powered neural stimulators that operate up to clinically relevant frequencies in excess of 100 Hz and these devices can be miniaturized to millimeter-scale and fully implanted.

Joshua C. Chen,Peter Kan,Zhanghao Yu,Fatima T. Alrashdan,Roberto Garcia,Amanda Singer,C. S. E. Lai,Benjamin W. Avants,Scott Crosby,Zhongxi Li,Boshuo Wang,Michelle Madden Felicella,A R Estrada Robledo,Angel V. Peterchev,S. Goetz,Jeffrey D. Hartgerink,Sunil A Sheth,Kaiyuan Yang,Jacob T. Robinson +18 more
TL;DR: In this paper , an endovascular wireless and battery-free millimetric implant for the stimulation of specific peripheral nerves that are difficult to reach via traditional surgeries is presented. But this requires invasive surgeries and the implantation of bulky devices (about a few centimetres in at least one dimension).
Wearable wireless power systems for 'ME-BIT' magnetoelectric-powered bio implants.
Fatima T. Alrashdan,Joshua C. Chen,Amanda Singer,Benjamin W. Avants,Kaiyuan Yang,Jacob T. Robinson,Jacob T. Robinson +6 more
TL;DR: In this paper, a battery-powered wearable magnetic field generator that can power a miniaturized MagnetoElectric-powered Bio ImplanT "ME-BIT" that functions as a neural stimulator was demonstrated.

MagNI: A Magnetoelectrically Powered and Controlled Wireless Neurostimulating Implant
Zhanghao Yu,Joshua C. Chen,Fatima T. Alrashdan,Benjamin W. Avants,Yan He,Amanda Singer,Jacob T. Robinson,Kaiyuan Yang +7 more
TL;DR: This paper presents the first wireless and programmable neural stimulator leveraging magnetoelectric (ME) effects for power and data transfer and includes robust system control and data recovery mechanisms under source amplitude variations (1-V variation tolerance).

Self-rectifying magnetoelectric metamaterials for remote neural stimulation and motor function restoration.
Joshua C. Chen,Gauri Bhave,Fatima T. Alrashdan,Abdeali Dhuliyawalla,Katie J Hogan,Antonios G. Mikos,Jacob T. Robinson +6 more
TL;DR: This metamaterial relies on nonlinear charge transport across semiconductor layers that allow the material to generate a steady bias voltage in the presence of an alternating magnetic field and can be used to wirelessly stimulate peripheral nerves to restore a sensory reflex in an anaesthetized rat model.
