First Claim
1. A body worn body parameter display device comprisinga housing having an array for displaying a value of the body parameter and a battery for energizing the array;
- means for connecting the battery to the array;
means carried by the housing for sensing a variable body pressure and delivering an electrical signal representative thereof, the sensing means including piezoelectric means having electrical output means;
means operatively connected to the housing for applying the sensing means in data transmitting relation to the body of an individual;
means connecting the electrical output means to the display array for displaying a value responsive to the electrical signal generated by the sensing means; and
means for generating and applying electricity to the battery and the array comprising the piezoelectric means and means for connecting the electrical output means to the display array and to the battery.

Abstract
There is disclosed a body parameter display device incorporated in a digital wrist watch for alternatively displaying time and a value representative of the body parameter. A pressure sensor incorporated in the device delivers an electrical output which is manipulated to deliver a signal proportional to the blood pressure sensing. In addition, the electrical pulses are manipulated to deliver a value representative of pulse rate. The pressure sensor also delivers an electrical output which is used to energize the watch and display mechanism and/or to charge a battery contained in the watch casing.
