However, supplying power and exchanging data with these devices remains a significant practical limitation. Wired connections are cumbersome and present a constant risk of infection, while implanted batteries require periodic replacement via surgery. Other proposed solutions require patients to wear heavy, cumbersome transmitters. <p><img src=\"https://s3.us-east-1.amazonaws.com/static.tto.c8e.ai/upitt/attachments/01789/0EMVv00000CPY9H.png\"></p></img>Top: schematic of the energy pad, depicted together with a cranial implant; bottom: prototype of the wireless power transfer system designed to be used with wireless neurostimulation.</p><p><h2>Description</h2>Researchers have developed three wireless power transfer (WPT) technologies to supply power to medical devices without wired connections, risk of infection, regular surgery, or impractical demands on the patient. The first WPT system is an energy pad made up of three parts: an easily-replaceable coin battery, a battery holder/circuit board, and a flexible foam pad that attaches to the skin. The circuit board converts battery power to AC current or radio-frequency (RF) energy, which flows through the body until it reaches a super-capacitor or rechargeable battery affixed to the implant. The circuit board can also then exchange information with the implanted device. Experiments  in vivo  have verified that these signals traverse the scalp. The second and third WPT systems also transmit power and information via RF energy, but in these cases, magnetic resonance is leveraged to minimize energy dissipation over space and within the body. In the laboratory, signals successfully bridged a 14.5cm air gap between the transmitter and receiver.</p><p><h2>Applications</h2>•\tWater capture\r<br>•\tWater purification</p><p><h2>Advantages</h2>•\tThe absorption process is completely passive and does not require external energy, special equipment, or any particular environmental conditions in order to absorb water. \r<br>•\tThe composite works well under a variety of environmental conditions. \r<br>•\tThe process to manufacture and process the composite is simple, not energy-intensive, and easy to scale to industrial quantities. \r<br>•\tThere is great potential for this technique to be modified in order to be utilized for the adsorption of other condensable vapors.</p><p><h2>Invention Readiness</h2>Prototype</p><p><h2>IP Status</h2><a target=\"_blank\" href=\"https://patents.google.com/patent/US8922065B2\">https://patents.google.com/patent/US8922065B2</a></p><p></p>","tags":["Surgery"],"file_number":"01789","collections":[],"meta_description":"Wireless power transfer for implanted devices with RF and magnetic resonance; enables safe, battery-free bioelectronics.","image_url":"https://s3.us-east-1.amazonaws.com/static.tto.c8e.ai/upitt/attachments/01789/0EMVv00000CPY9H.png","apriori_judge_output":"{\"scores\":{\"novelty\":2.0,\"potential_impact\":3.0,\"readiness\":2.0,\"scalability\":3.0,\"timeliness\":1.0},\"weighted_score\":2.4,\"risks\":[\"Age of invention (2008) implies patent/publication >15 years old\",\"unclear regulatory pathway\",\"limited evidence of clinical validation beyond in vivo verification\",\"competing WPT approaches; potential safety/regulatory hurdles\"],\"one_sentence_take\":\"The concept shows moderate novelty and impact but is substantially old (over 15 years) with limited publicly documented validation, raising significant commercialization and regulatory risks.\"}","lead_inventor_name":"Mingui Sun","lead_inventor_dept":"Med-Neurological Surgery","technology_type":"Medical Device","technology_subtype":"Implantable Medical Device","therapeutic_areas":[],"therapeutic_indications":[],"custom_tags":[],"all_tech_innovators":["Steven Andrew Hackworth","Xiaoyu Liu","Robert J.
