Miniature muscle displacement transducer

A transducer for sensing muscle displacement comprising:

• a curved beam having first and second spaced apart ends and being of a material having a relatively high degree of elastic compliance;
• first and second elongated prongs, physically attached to the first and second ends of said beam respectively, whereby said prongs are substantially parallel to one another and are disposed in a plane which is substantially perpendicular to a plane in which said beam is disposed, said prongs having sharpened ends to facilitate the attachment of said prongs to a muscle by inserting their sharpened ends thereinto, with the beam being in a plane above said muscle;
• and
• a strain gauge in physical contact with said beam for sensing the deformation of the latter as a result of changes in the linear spacing between said substantially parallel prongs due to muscle displacement.
