Abstract: A non-contact muscle signal sensing and assisting device, comprises a radar sensing module, a microprocessor and an electrical stimulation module. The radar sensing module continuously transmits a first microwave signal to a muscle bundle part and receives a corresponding reflected muscle signal, and performs a demodulation procedure on a second microwave signal and the reflected muscle signal to obtain and output a demodulated muscle signal. The microprocessor performs a muscle-movement signal characteristic processing procedure on the demodulated muscle signal to obtain a characterized muscle signal. The microprocessor obtains a muscle movement parameter according to the characterized muscle signal and controls the electrical stimulation module to emit a micro electrical stimulation signal to stimulate a reflex nerve when the muscle movement parameter fits an assistive condition, thereby stimulate muscle movement.

Abstract: A non-pressure continuous blood pressure measuring device, comprises: a radar sensing module, an electro-cardiac sensing module and a microprocessor. The radar sensing module includes at least a transmitter and a receiver, the transmitter continuously provides a pulse wave signal to an artery, the receiver receives a reflected pulse wave signal. The electro-cardiac sensing module includes at least an electrode; the electro-cardiac sensing module receives an electro-cardiac signal through the electrode. The microprocessor is in signal transmittable connection with the radar sensing module and the electro-cardiac sensing module. The microprocessor controls the radar sensing module and the electro-cardiac sensing module, and simultaneously receives the reflected pulse wave signal and the electro-cardiac signal. The microprocessor determines a blood pressure parameter of the artery according to the reflected pulse wave signal and the electrocardiography signal.
