Haptic human machine interface and wearable electronics methods and apparatus

An apparatus for mitigating type 2 diabetes, comprising:

• a housing configured as a pair of undershorts;
• a plurality of individually addressable electrodes supported by the housing, the individually addressable electrodes for applying stimulation electrical signals to skin of a user at a location of large muscle groups of the lower body to cause involuntary muscle contractions and detecting biometric electrical signals from the skin of the user, wherein a same individually addressable electrode of the plurality of individually addressable electrodes both detects the biometric electrical signals from the skin and applies the stimulation electrical signals to the skin, wherein the involuntary contractions metabolizes glycogen stored in the large muscle groups to mitigate type 2 diabetes;
• a signal detector for detecting the biometric electrical signals and a signal generator for generating the stimulation electrical signals;
• and an electrode multiplex circuit for addressing the plurality of individually addressable electrodes by routing the biometric electrical signals from the skin of the user through more than one of the plurality of individually addressable electrodes to the signal detector and routing the stimulation electrical signals from the signal generator through the more than one of the plurality of individually addressable electrode to the skin of the user;
• and a microprocessor for controlling at least one of the signal detector, the signal generator, the electrode multiplex circuit.
