Embodiments herein relate to a medical device for treating a cancerous tumor, the medical device having a first lead including a first wire and second wire; a second lead can include a third wire and fourth wire; and a first electrode in electrical communication with the first wire, a second electrode in electrical communication with the second wire, a third electrode in electrical communication with the third wire, and a fourth electrode in electrical communication with the fourth wire. The first and third electrodes form a supply electrode pair configured to deliver one or more electric fields to the cancerous tumor. The second and fourth electrodes form a sensing electrode pair configured to measure an impedance of the cancerous tumor independent of an impedance of the first electrode, the first wire, the third electrode, the third wire, and components in electrical communication therewith. Other embodiments are also included herein.

Disclosed are a single-arm electrocardiogram (ECG) signal measurement device and a single-arm ECG signal measurement method. The single-arm ECG signal measurement device includes a first sensing electrode, a second sensing electrode, a third sensing electrode, a fourth sensing electrode, a fifth sensing electrode, a sixth sensing electrode, and a computing circuit. The first sensing electrode, the second sensing electrode, the third sensing electrode, the fourth sensing electrode, the fifth sensing electrode, and the sixth sensing electrode receive physiological signals from six different positioning points located on an upper arm of a user. The computing circuit generates ECG signals according to the physiological signals, and generates a 12-lead ECG-like signal according to the ECG signals.

A system for providing a sound-based sensing of subjects comprising a network (10) of network devices (100) configured to perform a sound-based sensing. The network devices (100) are distributed in a sensing area (20) and communicate with each other based on RF signals. At least one network device (100) comprises a sound generator (120) to generate a sound signal (100) and/or a sound sensor (130) to detect the sound signal (101) from the sound generator (120) after a propagation through at least a portion of the sensing area (20) and to generate a sensing signal indicative of the detected sound signal. The sound generator (120) and the sound sensor (130) are arranged in different network devices (100). A sitting position detector (200) detects a sitting position of a subject in a sensing area based on the sensing signal from the sound sensor (130).

A device for measuring a bearing force exerted by the foot of a patient, the device including: a shell; an inner sole that is intended to support the foot of the patient and that is held in the shell, the shell and the sole being arranged so that, when the foot of the patient is bearing against the inner sole, the forces exerted by the foot of the patient on the inner sole are transmitted to the shell in a limited number of contact regions; sensors that are interposed between the shell and the inner sole in the contact regions, respectively, and that are each configured to deliver a signal representative of a force exerted on the corresponding contact region; and a processing unit connected to the sensors and configured to acquire the force signals delivered by the sensors.
