Has anyone heard of a contact-less EMS(Electrical Muscle Stimulation) device or know how to create o

The discussion addresses the possibility and nature of contact-less Electrical Muscle Stimulation (EMS) devices. It is clarified that EMS requires low voltage DC pulses delivered via direct skin contact to stimulate muscles, making contact-less EMS devices unfeasible. However, high frequency AC devices can induce skin heating without contact, similar to microwave ovens, but these do not stimulate muscles and only produce warmth. References are made to non-lethal crowd control technologies such as the Active Denial System (ADS), which uses directed energy to cause discomfort or heat sensations at a distance. These systems operate on principles similar to microwave radiation and can be dangerous if misused, potentially causing harm such as blindness or sterility. Shielding effectiveness varies: metal can block such radiation effectively, while wood and rubber provide limited or no protection. The discussion also touches on the challenges of detecting and defending against such directed energy devices, with suggestions to develop detection systems rather than construction methods. The conversation includes concerns about covert use of such devices by security agencies and the need for protective measures, including inquiries about eyewear capable of shielding microwave attacks.
