A method for configuring a myoelectrically controlled prosthetic system with a prosthesis socket and several lead electrodes for recording electric muscle activities, featuring the steps: placement of a surface electrode arrangement comprising several surface electrodes around the circumference of a residual limb, recording of electric muscle activity in muscles of the residual limb as electromyograhic signals, the activity being recorded by the surface electrodes, evaluation of the myoelectric signals with regards to the distinctness of the signals, selection of the control procedure that is to be used to control the prosthesis system, based on the evaluation of the distinctness of the signals, and fixing of the lead electrodes to the prosthesis socket.

An optical physiological sensor can be integrated into a wearable device and can comprise a substrate having an optical center, a first emitter group of light emitting diodes (LEDs) positioned adjacent to the optical center of the substrate and spaced at an offset from the optical center, a second emitter group of LEDs positioned adjacent to the optical center of the substrate at an offset to the optical center and spaced at an offset from the optical center opposite the first emitter group of LEDs relative to the optical center, and a plurality of detectors arranged in a spatial configuration that surrounds the first and the second emitter group. Each of the plurality of detectors can be positioned on the substrate a same distance away from the optical center of the substrate.

A wearable device for monitoring physical activity of a user, the wearable device being reversibly attachable to a chest strap and an arm strap. The wearable device comprises an ECG sensor arranged to collect ECG measurements of the user only when the wearable device is attached to the user's chest by the chest strap, and a PPG sensor arranged to collect PPG measurements of the user when the wearable device is attached to the user's arm or wrist by the arm strap. The wearable device also comprises control circuitry arranged to switch the wearable device between an ECG only mode and a PPG only mode. In the ECG only mode, the control circuitry is configured to control the ECG sensor to collect ECG measurements but prevent the PPG sensor from initiating PPG measurements. In the PPG only mode, the control circuitry is configured to control the PPG sensor to initiate PPG measurements but prevent the ECG sensor from collecting ECG measurements.
